DIGITAL FREQUENCY COUNTER -4 (SIGNAL CONDITIONER AND INPUT CIRCUIT UNIT)

Objectives of this experiment:

Signal conditioner and input circuit unit accepts sine wave and shapes into a square wave of the same frequency, after its amplitude is properly adjusted to be about 5V. Invariably the input signal, whose frequency is to be measured, is a sine wave signal Its amplitude is amplified attenuated before it is fed to a Schmitt trigger, which converts sine waves into square waves of the same frequency. All the units are essential for complete working.

Built in regulated power supply: +15V/150mA, -15V/150mA.
Input Supply: 230 VAC/50Hz mains operated.
Dimension: 27cms x 17cms x 10cms.
