title: Fast and simple photometric signal processing unit.
abstract: A simple and fast photometric signal processing unit has been constructed using some of the commonly available linear and digital integrated circuits. A common mode rejection ratio of 75 dB, based on the subtraction of the output and reference signal, and a rise time of 0.2 mus have been achieved with this instrument.
