Sampling Theorem Formula 1-D: One of the most important applications of digital filtering is the processing of sequences of samples derived from continuous or analog signals. This is made possible…
Synchronous Vibrator and Synchronous Chopper: Low dc current may be transformed into a high voltage dc by simple chopper action. Although an inductive type transformation process is required, the outÂput…
Diode Bridge Type Modulator with Transformer Coupling: Diode Bridge Type Modulator - Figure 14.33 shows a silicon diode ring modulator with an associated ac coupled dc amplifier. The amplifier itself…
Signal Conditioning System: Signal Conditioning System - The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first stage…
Optical Pyrometer Working Principle: Optical Pyrometer Working Principle - Any metallic surface when heated emits radiation of different wavelengths which are not visible at low temperature but at about 550…
Pyrometer Working Principle: When temperature being measured is very high and physical contact with the medium to be measured is impossible or impractical, optical pyrometer based on the principle of…
Thermistor Working Principle: Thermistor Working Principle - The electrical resistance of most materials changes with temperature. By selecting materials that are very temperature sensitive, devices that are useful in temperature…
Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle - The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, feedback amplifier. This configuration has a very…
