Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive…
Microprocessor Based Instruments: Microprocessor Based Instruments - Digital instruments are designed around digital logic circuits without memory. The use of microprocessors as an integral part of measuring instruments has given…
Digital Capacitance Meter Block Diagram: Digital Capacitance Meter - Since the capacitance is linearly proportional to the time constant, when a capacitor is charged by a constant current source and…
Digital Phase Meter Block Diagram and Working Principle: Digital Phase Meter - The simplest technique to measure the phase difference between two signals employs two flip-flops. The signals to be…
Different Modes of Operation of Electronic Counter: The decade counter can be easily incorporated in a commercial test instrument called an electronic counter. A decade counter, by itself, behaves as…
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…
