ABSTRACT:
Circuits for matching amplitudes and/or frequencies of analog signal waveforms stored in two analog signal delay elements (hereinbelow, ADMs) are desclosed. In order to equalize amplitudes of the analog signal waveforms stored in two ADMs, peak values of the amplitudes of the analog signal waveforms stored in the two ADMs are compared, then based on the comparison result, gain of an amplifier for amplifying or attenuating amplitudes of either one of the analog waveforms is controlled. In order to equalize frequencies of the analog signal waveforms stored in the two ADMs, a term of duration between adjacent peaks of the analog signal waveforms stored in the two ADMs are compared, and then based on the comparison result, the circulation speed of the analog signal waveform in one of the ADMs is controlled.
