Problem Title: Design and implement a digital processing-based speech quality enhancement system to improve the signal to noise ratio (SNR) of recorded speech signal. Problem Description: Design and implement a digital processing-based speech quality enhancement system for voice signal recorded by you. The details of the design constraints are as follows: 1. Required to record Voice in a noisy environment and perform statistical analysis of the recorded audio signal to find: o Mean o Standard Deviation o Variance o No of Zero Crossings o SNR o Frequency spectrum 2. Based on analysis, design and implement a digital signal processing system for the enhancement of speech signal.

Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.
