A Simple Electric Motor: Variable speed drives in the industry employ a simple electric motor as their drive motors mainly because they enjoy several specific advantages, such as overload capacity,…
Simple Cylindrical Cavity Wavemeter: Resonant cavities find extensive use as wavemeter at microwave frequencies. They enjoy high accuracy, mechanical simplicity, and a large physical size in proportion to the wavelength…
Resonant Coaxial Wavemeter: A Resonant Coaxial Wavemeter line such as illustrated in Fig. 16.1 and operating as a resonant system can be used to measure frequencies in the range of…
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…
Block Diagram of a Digital Filtering Processor: The implementation of any digital filtering consists of a series of multiplications of samples of the input and/or output signals by constants, and…
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…
Higher Order Filter Design: Higher Order Filter Design - From the preceding discussion on filters we can conclude that in the stop band the gain of the filter changes at…
Classification of Active Filters: An electric filter is often a frequency selective circuit that passes a specified band of frequencies and blocks or attenuates signals of frequencies outside this band.…
