ABSTRACT:
A high frequency discriminator is disclosed with a phase shift circuit using a piezoelectric crystal and a series connected load resistor. The voltage across the load resistor is shifted in phase an amount corresponding to the deviation of the input signal voltage from its center frequency. This phase shifting circuit may be connected in cascade with a 90.degree. phase shift circuit to produce the quadrature voltage for the discriminator. The discriminator provides very low distortion in the output.
