Digital signal processing device and digital signal processing method |
摘要 |
An apparatus for processing a digital signal that generates a one-bit output signal using a delta-sigma modulation apparatus, which includes a quantizer for quantizing an integrated output of a sixth integrator to generate a one-bit output signal that is send to respective integrators through an adder under feedback processing to output the one-bit output signal to the outside of a six-order Delta-sigma modulator, and a control unit for generating a control signal that controls the feedback loop signal from the quantizer so as to change the signal level of a signal component of the audio frequency band of the one-bit output signal. The control unit receives an integrated output from a second integrator being an input side integrator of the six-order delta-sigma modulator.
