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 linear shift invariant systems have…
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 sequence {y(n)} A system of…
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 due to the results and…
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 values of their variables, that…
Introduction to Digital Filtering: It has been seen that control of the band width of a circuit or signal is of paramount importance in optimizing the measurement of a signal. Formerly band width control was…
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 flat amplitude versus frequency response…
Universal Active Filter using Op Amp: With the advance of integrated circuit technology, integrated circuits with improved capabilities are appearing in ever increasing numbers. Innovative design methods and fabrication procedures have not only helped to…
All Pass Filter Design: The All Pass Filter Design is one that passes all frequency components of the input signal without attenuation. Any ordinary wire can be used to perform this charÂacteristic but the most…
Band Reject Filter Circuit: In this Band Reject Filter Circuit, frequencies are attenuated in the stop band and passed outside it, as shown in Fig. 15.20(b). As with band pass filters, band reject filters can…
Band Pass Filter Circuit Diagram: A Band Pass Filter Circuit Diagram designed to pass signals only in a certain band of frequencies while rejecting all signals outside this band. There are basically two types of…
