发明名称 Signal compression/expansion device and mobile communication terminal
摘要 A signal compression/expansion device has a frequency band division circuit, a compression/expansion circuit and a band synthesis circuit. The frequency band division circuit divides an input signal into a plurality of frequency bands. The compression/expansion circuit compresses/expands the input signal in accordance with a level of the input signal with a predetermined gain. The frequency band synthesis circuit adds the plurality of input signals having being compressed/expanded. <IMAGE>
