Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased…
Spectrum Analyzer Block Diagram: Spectrum Analyzer Block Diagram - The most common way of observing signals is to display them on an oscilloscope, with time as the X-axis (i.e. amplitude…
Heterodyne Wave Analyzer: Wave analyzers are useful for measurement in the audio frequency range only. For measurements in the RF range and above (MHz range), an ordinary wave analyzer cannot…
Frequency Selective Wave Analyzer: The Frequency Selective Wave Analyzer consists of a very narrow pass-band filter section which can be tuned to a particular frequency within the audible frequency range…
What is Wave Analyzer?: It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure the amplitude…
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…
Chopper type DC Amplifier Voltmeter (Microvoltmeter): Chopper type DC Amplifier Voltmeter the dc input voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back…
