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…
Ramp Technique of Digital Voltmeter: Ramp Technique - The operating principle is to measure the time that a linear ramp takes to change the input level to the ground level,…
Function Generation and Linearisation: An important aspect of the closed loop control system is the use of Function Generation and Linearisation, e.g. in the control of induction motors there exists…
CT Scan Working Principle: CT Scan Working Principle - Biomedicine is one area in which the use of digital signal processing techniques had had great impact. Computer tomography A recent…
Modern Radar Systems Analysis: Modern Radar System are of great importance for both military and civil applications. The main problem of a typical radar system is the detection of return…
Bandpass Analysis: There exist many practical situations in which multiple filtering and band pass analysis are required. In multiple filtering, one specific operation (for example low pass, high pass, band…
Frequency Domain Representation: Frequency Domain Representation - A very important representation of discrete time systems can be obtained in terms of sinusoidal or complex-exponential signals. This is possible because the…
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…
