Notes:
A simple computer-controlled digital lock-in amplifier is presented. It has been designed as an interface for a personal computer with a minimum number of components. Its simplicity and the fact that all parameters are computer controlled makes the amplifier well suited for multichannel phase-sensitive detection. A comparison with a commercial analog lock-in amplifier is presented.
