RX Meter Circuit in Measuring Instruments: An RX Meter Circuit in Measuring Instruments is used to measure the separate resistive and reactive components of a parallel Z network. It is…
Digital Fourier Analyzer: The basic principle of a Digital Fourier Analyzer is shown in Fig. 9.14. The Digital Fourier Analyzer converts the analogue waveform over time period T into N…
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…
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…
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…
Beat Frequency Oscillator (BFO) | Block Diagram | Working and Limitations: In this Beat Frequency Oscillator, the outputs of two RF oscillators are applied to a square law detector and…
