摘要： When reception of multiplexed PSK modulated waves BPSK and 8PSK starts, a selector (16C) of a demodulation circuit (IC) read higher-order three bits ΔΦ(3) of the phase error data corresponding to outputs I′ and Q′ of a remapper (7) for performing absolute phasing from a phase error table for BPSK out of tables provided for respective types of modulation methods. A reception signal phase rotation angle detection circuit (8C) detects the phase rotation angle corresponding to a bit “1” of a frame sync signal of a received symbol stream from ΔΦ(3) and the MSB of the output I′ of the remapper (7) and outputs the phase rotation angle to the remapper (7) to allow the remapper (7) to perform absolute phasing. The selector (16C) reads phase error data corresponding to the received symbol data after absolute phasing output from the remapper (7) from the phase error table corresponding to the modulating method identified by a transmission configuration identification circuit (9), outputs the phase error data to a D/A converter (17), corrects the phase of carrier waves for orthogonal detection, and causes the difference in phase between the received signal point and the transmission signal point to be constant.

摘要： A clock regeneration circuit for regenerating a clock signal for demodulating data from an AM data multiplex modulated signal where digitally modulated signals are multiplexed in the same frequency band as those of an amplitude-modulated signal at the same time. The carrier for an amplitude-modulated signal is extracted from an AM data multiplex modulated signal where digitally modulated signals are multiplexed in the same frequency band as those of the amplitude-modulated signal at the same time through a band-pass filter, and the oscillation frequency of a voltage-controlled oscillator is controlled by the output of a phase comparator through a loop filter. The oscillation output of the voltage-controlled oscillator is supplied to a direct digital synthesizer and the phase of the carrier extracted through the band-pass filter is compared with the phase of the output of the direct digital synthesizer using the phase comparator. The oscillation output of the voltage-controlled oscillator is then synchronized with the carrier for the amplitude-modulated signal to produce a clock signal for demodulating data.

摘要： I and Q symbol streams are demodulated from a received signal of a wave to be PSK-modulated in which BPSK-modulated frame-synchronizing signal and superframe-identifying signal respectively having a 20-symbol length and an 8 PSK-modulated digital signal are time-multiplexed by a demodulating circuit (1). BPSK-demapped bit streams B0 to B3 are generated by a BSPK demapper (3) in accordance with criterion border lines obtained by rotating a basic BPSK criterion border line and a basic criterion border line whose received-signal points are the same as Q-axis on, I-Q phase plane by &pgr;/4, 2&pgr;/4, and 3&pgr;/4 counterclockwise. When a pattern having is a difference of several bits at most from a frame-synchronizing signal is captured from B0 to B3 by first comparing circuits 60 to 63 and thereafter, a pattern having a difference of several bits at most from a superframe-identifying signal is captured by second comparing circuits 64 to 67 after a predetermined certain time, a frame-synchronizing-signal-capturing-signal generating circuit (90) outputs a frame-synchronizing-signal capturing signal (SYN).

摘要： There is provided a synchronization acquiring circuit for stably acquiring frame synchronization without pseudo-synchronization lock when the frame synchronization is acquired in reception at the time of a low C/N. The synchronization pattern of a received frame is detected by a frame synchronization detecting circuit 2. The bits of the synchronization pattern of the received frame are compared with those of a frame synchronization pattern on the transmitting side by a frame synchronizing circuit 5 to obtain the number of coincided bits. The frame synchronization is regarded as detected when the obtained number of bits of each frame is equal to or larger than the correlation detection value.

摘要： A digital broadcasting receiver in which one decoder decodes both Reed-Solomon codes for TMCC and Reed-Solomon codes of an MPEG2-TS packet of a main signal. The received data is divided into a main signal and a TMCC signal. When the separated main signal is subjected to deinterleaving by a deinterleaving circuit (503), the burst symbol signal is eliminated, and the TMCC signal separated subsequent to the main signal in the last frame of a superframe is added by a selector (509). The received data to which the TMCC signal is added is decoded by a basic Reed-Solomon code decoder (510) so as to carry out the error correction of the main signal and the TMCC signal.

摘要： An exposure apparatus and an exposure method that prevents a decrease in throughput, while maintaining high mask alignment accuracy regardless of frequent mask exchange. When a lot of wafers undergoes an exposure process, the patterns of two reticles are overlapped and exposed on a single shot area of a wafer. In this case, when each reticle is used for the first time, the positions of all alignment marks on the reticle are measured (fine position measurement). The reticle is positioned based on the measurement result. If the reticle is used again, only one set of the alignment marks is measured, the fine position measurement result is corrected based on the measurement result, and the reticle is positioned based on the corrected measurement value.

摘要： An MSK modulator providing a high precision digital phase adjustment with a simple circuit structure. A sample data of a sine wave or cosine wave is read from a memory at an address calculated from an initial address value. The initial address value is set in accordance with the amount of phase to be adjusted. A predetermined number of sample data read from the memory is held, outputted in a predetermined order, and converted into an analog signal. The phase of the converted analog signal is adjusted, and thereafter multiplied by an input baseband signal. The multiplied result is outputted as a modulation signal.

摘要： A magnetic recording and reproducing apparatus which includes a set of loading members for drawing out a magnetic tape accommodated in a tape cassette and wound around a set of reels disposed to contact the same plane. The tape storing portions of the tape cassette are directed along part of the outer peripheral surface of a rotary head cylinder in an approximately M-shape, and a single inclining member is provided in the vicinity of one tape storing portion for causing a tape travelling reference face of the magnetic tape drawn out from the tape storing portion to be inclined. The first loading member corresponding to the tape storing portion is rotatably supported at right angles with respect to the tape travelling reference face of the magnetic tape inclined by the inclining member, while the other loading member corresponding to the other tape storing portion is rotatably supported at right angles with respect to the tape travelling reference face of the magnetic tape drawn out from the other tape storing portion.
