Classification: CPC H | IPC H

Claim 15:
16. The apparatus according to claim 15, wherein the process further includes:
performing isoprobabilistic processing and isospectral processing cyclically on the input signal by taking a reference signal as a standard, until an obtained signal meets on a target probability distribution and a target spectrum at the same time, so as to obtain a signal after the notch operation;
wherein,
a probability distribution of the reference signal meets the requirement on the target probability distribution;
the isoprobabilistic processing refers to processing that makes a probability density distribution of the output signal identical to that of the reference signal;
the isospectral processing refers to processing that makes a power distribution of the spectrum of the output signal close to a requirement on a power distribution of the target spectrum.
