A synchronous detector is described which consists of an amplifier with electronic switches in the negative-feedback circuits. The range of operating frequencies is 0. 5 Hz to 100 kHz, the dynamic range is greater than 100 db, the sensitivity is less than 10 mu v, the suppression of noncoherent noise is greater than 80 db, the suppression of the input signal's 3rd and 5th harmonics is greater than 30 db, and the linearity of the transmission factor is 0. 1%.
