Ward Leonard Drive Transfer Function: In the classical Ward Leonard Drive Transfer Function, the dc drive motor having constant excitation is supplied from a variable voltage generator, as shown in…
Transfer Function of a Field Controlled DC Motor: The speed of a dc motor can be varied by varying the field current. The speed can be increased beyond base speed…
Time Delay Circuit: Several choices are available in the selection of suitable circuits for obtaining Time Delay Circuit depending on the magnitude of the time delay required. Delays of the…
Step Function Response: The step function response consists of applying an instantaneous change in the control means and then recording graphically the result of the change on the measured variable.…
Data Loggers Function: The basic Data Loggers Function is to automatically make a record of the readings of instruments located at different parts of the plant. Data loggers measure and…
Function Generator Block Diagram: A Function Generator Block Diagram produces different waveforms of adjustable frequency. The common output waveforms are the sine, square, triangular and sawtooth waves. The frequency may…
Universal Counter Timer: All measurements of time period and frequency by various circuits can be assembled together to form one complete block, called a Universal Counter Timer. The universal counter…
Working Principle of Digital Multimeter: Analog meters require no power supply, they give a better visual indication of changes and suffer less from electric noise and isolation problems. These meters…
