Abstract
It has already been pointed out that the transducers used in a laboratory to convert the quantities under observation into suitable electric signals rarely give sufficient output to actuate an indicating device directly. The electric output from photocells, strain gauges, glass electrodes, thermistors, etc., all need to be increased, i.e. amplified, before the signal can be suitably recorded or indicated. Some intermediate electronic apparatus must therefore be provided between the transducer and indicator to effect the necessary amplification. The design of a suitable amplifier depends upon the transducer and indicator used, upon the power required and upon the frequency of the signal that must be amplified.
