8. Digital Signal Processing Laboratory:

The experiments corresponding to the Signals and Systems and Digital Signal Processing are performed in this Laboratory. The experiments including fundamental signal operations, analysis of LTI systems (linear convolution), Fourier analysis of periodic and non-periodic signals both in continuous and discrete –time, frequency domain representation of signals etc. are performed for the signals and systems laboratory. The digital signal processing (DSP) lab has both software and a hardware component. In the software part, students carry out a number of simulations, illustrating some of the fundamental concepts and applications of digital signal processing, such as quantization, sampling and aliasing, block processing by convolution using overlap save and overlap add method, signal enhancement and noise reduction filters, direct, canonical, and cascade realizations of digital filters, spectral analysis by the DFT and FFT, the design of IIR, and FIR filters for band pass, band stop, low pass and high pass filters, and digital audio effect applications. The hardware part of the lab illustrates the programming of real-time signal processing algorithms. Through this laboratory the students would be able to understand the handling of discrete/digital signals, the basic operations of signal processing, the design and analyze linear time-invariant (LTI) systems and compute its response, analyze the spectral characteristics of signals using Fourier analysis, analyze the systems using Laplace transform and Z-transform, the design IIR, and FIR filters for bandpass, band stop, low pass, and high pass filters and design the signal processing algorithm.
