Harmonic Distortion Analyzer: A Harmonic Distortion Analyzer measures the total harmonic power present in the test wave rather than the distortion caused by each component. The simplest method is to…
Modern Laboratory Signal Generator Block Diagram and its Working: Modern Laboratory Signal Generator - To improve the frequency stability, a single master oscillator is optimally designed for the highest frequency…
Attenuators: Attenuators are designed to change the magnitude of the input signal seen at the input stage, while presenting a constant impedance on all ranges at the attenuator input. A…
Automation in Digital Instruments: Automation in Digital Instruments - One of the advantages of digital multimeters is their ease of operation. The reading is easy to take and does not…
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…
Principles of ADC (Analog to Digital Conversion): Principles of ADC - The input signal is compared with an internally generated voltage which is increased in steps starting from zero. The…
True RMS Voltmeter: True RMS Voltmeter - Complex waveform are most accurately measured with an rms voltmeter. This instrument produces a meter indication by sensing waveform heating power, which is…
