Abstract:
An emphasis signal generating circuit includes: a branch and delay unit configured to branch an input signal, delay a branched signal, and output a first delayed signal; a high-frequency extraction unit configured to extract at least one of high-frequency components of the input signal and the first delayed signal to output a high-frequency signal; and an addition and subtraction unit configured to add and subtract the input signal, the first delayed signal, and the high-frequency signal.
