Abstract	It is often necessary in communication systems to detect very small signals that are buried in noise. One device used to accomplish this is a lock-in amplifier. Initially the theory of operation is considered. Then the circuit design of a low cost lock-in amplifier is given. The amplifier, employing linear integrated circuits, has a frequency range from 200 to 30 KHz and can detect a 10 nanovolt signal buried up to 60 dB below the noise level. Experimental results are given for a variety of input signal conditions.
