摘要： A circuit having versatility synthesizes one-bit digital signals to generate a ternary signal. The pulse synthesizing circuit synthesizes one-bit digital signals from two DFFs to generate a ternary signal. The pulse synthesizing circuit has a first NOR gate, a second NOR gate, a third NOR gate, and three switches. The first switch is connected to a first electric potential, the second switch is connected to a second electric potential, and the third switch is connected to a third electric potential. The first to third switches are turned on/off according to logical values of the signals from the two DFFs, and any of the first electric potential, the second electric potential, and the third electric potential is set as an output potential so that a ternary signal is generated.

摘要： To resolve volume shortage of middle and high band of speaker reproduction sound. A DSP 4 performs LPF processing to extract low frequency component of an audio signal to which the first volume processing is performed, DRC processing to compress the audio signal to which the LPF processing is performed in case that the audio signal to which the LPF processing is performed is not less than a predetermined signal level, HPF processing to extract high frequency component of the audio signal to which the first volume processing is performed, second volume processing to attenuate the audio signal to which the HPF processing is performed based on the volume value that is received, and synthesis processing to synthesize the audio signal to which the DRC processing is performed and the audio signal to which the second volume processing is performed.

摘要： Provided is a modulation circuit that can correct an output state in real time and reliably modulate an input signal to output the modulated signal. The signal modulation circuit includes a subtractor, an integrator, a chopper circuit, a frequency divider, and a D-type flip-flop. A delay circuit of a sigma delta modulation circuit is not provided to a feedback circuit, and a signal is delayed and quantized in the D-type flip-flop. The chopper circuit inserts a zero level at timing synchronized with a clock signal, so that pulse density modulation is performed.

摘要： A signal modulation circuit includes a feedback circuit configured to generate the feedback signal for feeding back a drive signal from a driver circuit to an input signal. The feedback circuit includes at least first and second resistors connected together in series, the second resistor having a higher resistance value than that of the first resistor. One end of the first resistor is connected to a subtracter, and one end of the second resistor is connected to the driver circuit. A first line distance as the line length between one end of the first resistor and the subtracter and a second line distance as the line length between one end of the second resistor and the driver circuit are set shorter than a third line distance as the line length between the other end of the first resistor and the other end of the second resistor.
