摘要： A signal under measurement is transformed into a complex analytic signal using a Hilbert transformer and an instantaneous phase of this analytic signal is estimated. A linear phase is subtracted from the instantaneous phase to obtain a phase noise waveform. The phase noise waveform is sampled in the proximity of a zero crossing point of a real part of the analytic signal. A differential waveform of the sample phase noise waveform is calculated to obtain a differential phase noise waveform. An RMS jitter is obtained from the phase noise waveform, and a peak-to-peak jitter is obtained from the phase noise waveform.

摘要： A clock waveform XC(t) is transformed into a complex analytic signal using a Hilbert transformer and an instantaneous phase of this analytic signal is estimated. A linear phase is subtracted from the instantaneous phase to obtain a varying term &Dgr;&phgr;(t). A difference between the maximum value and the minimum value of the varying term &Dgr;&phgr;(t) is obtained as a peak-to-peak jitter, and a root-mean-square of the varying term &Dgr;&phgr;(t) is calculated to obtain an RMS jitter.

摘要： A signal under measurement is transformed into a complex analytic signal using Hilbert transformation to estimate an instantaneous phase of the signal under measurement from the complex analytic signal. A least mean square line of the instantaneous phase is calculated to obtain a linear instantaneous phase of the signal under measurement, and a zero-crossing timing of the signal under measurement is estimated using an interpolation method. Then a difference between the instantaneous phase and the linear instantaneous phase at the zero-crossing timing is calculated to estimate a timing jitter sequence. A jitter of the signal under measurement is obtained from the jitter sequence.

摘要： According to one embodiment, a semiconductor memory device includes a memory array, an address counter, an address detecting circuit and a control circuit. The memory array has a plurality of memory cells arranged at crossing positions of word lines and bit lines. The address counter increments an address including a row address and a column address in synchronism with a clock to sequentially output the incremented addresses. The address detecting circuit detects an address previous to an address including a row address to which the row address is switched at the address output from the address counter to output a detection signal. The control circuit performs a precharging operation to the bit lines connected to the memory cells according to the detection signal output from the address detecting circuit.

摘要： A digital copying machine develops an electrostatic latent image formed on a photosensitive drum with toner, and transfers the developed image onto a sheet. In forming images on the photosensitive drum successively, three types of test patterns are formed in order in intro-image areas between image forming areas, and AIDC is made. The first test pattern is a low-density pattern, the second test pattern is an intermediate-density pattern, and the third test pattern is a high-density pattern.

摘要： According to one embodiment, a semiconductor memory device includes a first memory, a second memory and a control circuit. The first memory includes a first bank number. The second memory includes a second bank number larger than the first bank number. The control circuit controls a precharge operation with respect to bit lines provided in the first and second memories. When performing, with respect to the first memory, a synchronous operation that is effected in synchronization with a clock, the control circuit changes over a second precharge operation to an operation time different from a first precharge operation during a period from the end of the initial first precharge operation to the start of the subsequent second precharge operation after receiving an address.
