ABSTRACT:
A method for the multiplication of electrical signals comprises modulating the signals to be multiplied with functions having positive and negative values, multiplying the modulated signals together, demodulating the resulting product with demodulation functions which are the reciprocal of each modulation function, and then averaging the demodulated signal. The modulation circuit comprises an inverter, control signal gated FET's, and an operational amplifier of which the output is the desired modulated signal. A circuit comprising a shift register and an Exclusive-Or gate provides statistical alteration of the cycle duration of the modulation and demodulation functions.
