Digital Signal Processing Lab
Digital Signal Processing Laboratory(EC-593)
General information about the Laboratory: Digital Signal Processing laboratory is situated 2nd floor, room no. 316B.Geometric area of this lab is about 900 square feet. According to present curriculum B-Tech (ECE) 5th Semester Students perform experiments on Digital Signal Processing Laboratory.Digital Signal Processing (DSP) Laboratory can be described as the processing of signals using digital techniques or digital computers. A signal is a piece of information in binary or digital form. Digital Signal processing techniques improve signal quality or extract important information by removing unwanted part of the signal.Digital Signal Processing accounts for a substantial proportion of the world market for electronic devices. And therefore, the leading electronics manufacturers have invested heavily in DSP technology.
