ABSTRACT:
An auto-equalizer for passing data pulses of the type which tries to restore the relative amplitude of the first and third harmonics of the data signal frequency while deemphasizing the amplitude of other higher harmonics. The present invention accomplishes the relative harmonic amplitude restoration by controlling the resistance in a tuned circuit element affecting the gain of a signal passing amplifier. The adjustment of the resistance directly affects the Q of the tuned circuit involved.
