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…
What is Digital System?: Fundamental Properties of 1-D Digital System : A digital system can be defined as an operator which transforms an input sequence { x(n)} to an output…
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…
Properties of Linear Digital Filters: The properties of linear digital filters defined as transformations of discrete functions are described in the following. Discrete Functions Equation are defined only for discrete…
Low Pass Filter Circuits: The Low Pass Filter Circuits of Fig. 15.7 is commonly used for low pass active filters. The filtering is done by the use of an RC…
Types of Filters in Electronics: Types of filters in electronics may be of any physical form—electrical, mechanical, pneumatic, hyÂdraulic, acoustical, etc. The most commonly used filters are of the electrical…
Varactor Diode Symbol: A specially processed junction diode that assumes the properties of a variable capacitor (about 5 - 250 pf) when its dc reverse voltage is varied is called…
Differential Instrumentation Amplifier Transducer Bridge: Figure 14.25 shows a simplified circuit of a Differential Instrumentation Amplifier Transducer Bridge. In this circuit a resistive transducer (whose resistance changes as a function…
