A symmetrical discriminator and demodulator having two radio wave tuned circuits disposed parallel. The discriminator and demodulator has a common grounding connection for one end of each radio wave tuned circuit. The opposite end of each tuned circuit is connected to a coupling capacitor to couple the tuned circuit to a demodulator. Two pairs of diodes are connected to each capacitor, the two pairs of diodes being connected together in a head to tail fashion in a cross-over figure-8 arrangement. The alternate junctures of said diode pairs are connected to two output coupling capacitors to provide a demodulated signal output. The symmetrical arrangement permits the use of extremely sensitive MOS-FETs in discriminator and demodulator circuitry.
