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 pulses; this substantially corresponds to…
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 pass, etc.) is required to…
Typical Digital Filtering Operations: Digital filters in fact can be applied in many different parts of a signal and image processing transmission system. Two typical examples of systems in which typical digital filtering operations can…
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 of the additions of these…
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 considered along with its application…
IIR Digital Filter Design Methods: IIR Digital Filter Design Methods - Fettveis first suggested the use of one port reflection coefficients for the transfer of analog filter properties from the analog domain to the digital…
FIR 1-D Digital Filter Design (The Window Method): We describe the Fourier series technique as the first design method of 1-D FIR digital filters [Eq. (15.83)]. In this Digital Filter Design Window Method, given a…
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 analysis of signals, the continuous…
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…
