Signal and Systems Matlab GUI based analysis

Description: This Signal and Systems based Project takes a sound file in.wav format and performed a detailed analysis, as well as filtering of the signal. The project is programmed in matlab and provides and easy to use GUI interface and provides user to perform various functionalities. Programming: function varargout = pro_sns_p2(varargin) % PRO_SNS_P2 M-file for pro_sns_p2.fig % PRO_SNS_P2, by itself, creates a new PRO_SNS_P2 or raises the existing % singleton*. % % H = PRO_SNS_P2 returns the handle to a new PRO_SNS_P2 or the handle to % the existing singleton*. % % PRO_SNS_P2('CALLBACK',hObject,eventData,handles,...) calls the local % function named CALLBACK in PRO_SNS_P2.M with the given input arguments. % % PRO_SNS_P2('Property','Value',...) creates a new PRO_SNS_P2 or raises the % existing singleton*. Starting from the left, property value pairs are % applied to the GUI before pro_sns_p2_openingfcn gets called. An % unrecognized property name or invalid value makes property application % stop. All inputs are passed to pro_sns_p2_openingfcn via varargin. % % *See GUI Options on GUIDE's Tools menu.
