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…
IIR Filter Design 1-D: In this section some practical considerations relating to the methods for the design of IIR Filter Design filters are presented. In particular, the bilinear transform is…
Fast Fourier Transform Formula: The Fast Fourier Transform Formula is a computational tool which facilitates signal analysis, such as power spectrum analysis and filter simulation using digital computers. In digital…
Types of Active Filters: There are basically four useful Types of Active Filters. Namely Butterworth Filter Chebyschev Filter Bessel Filter Elliptic Filter Butterworth Filter: The Butterworth filter has an essentially…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
What is a Filter Circuit?: A network designed to attenuate certain frequencies but pass others without attenuation is called a filter. A filter circuit thus possesses at least one pass…
Transistor Chopper Circuit: Transistor Chopper Circuit - A single transistor used as a dynamic switch to convert low level dc signal to an ac waveform is shown in Fig. 14.34.…
Magnetic Modulator: The most reliable substitutes for electromechanical choppers are magnetic modulators. These devices reach a null stability as low as 10 μV, but their response time is often less…
