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…
Wien Bridge Circuit Diagram: The Wien Bridge Circuit Diagram shown in Fig. 11.27 has a series RC combination in one arm and a parallel combination in the adjoining arm. Wien's…
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…
