Speech signal is analog in nature. The maximum frequency component present in human voice signal can be taken approximately as 3-4KHz.In many modern day applications, it is often required to process the speech signal in digital domain. For this reason, digital processing of analog speech signal is highly important. Delta Modulation is a scheme that can be used to implement digital representation of analog speech signal. In this work, the speech signal is modulated and demodulated using a very simple technique, known as Delta Modulation(DM). Moreover, several other aspects like silence removal, Signal to Noise ratio (SNR) calculation and Power Spectral Density(PSD) analysis has also been carried out.
