implementation of pcm pulse code modulation on speech signals in matlab

Pulse-code modulation (PCM) is a method used to digitally represent sampled analog signals. It is the standard form of digital audio in computers, Compact Discs, digital telephony and other digital audio applications. In a PCM stream, the amplitude of the analog signal is sampled regularly at uniform intervals, and each sample is quantized to the nearest value within a range of digital steps.Linear pulse-code modulation (LPCM) is a specific type of PCM where the quantizati ....etc

pulse position modulation code in matlab

PWM (Pulse Width Modulation) can be easily generated in MATLAB using simple MATLAB functions. We have already discussed about PWM generator circuit using 741 Op-amp in previous posts. In PWM, width of the pulses are varied according to the amplitude of AF message signal. PWM is basically an analog pulse modulation technique. It does modulation of the duty cycle of the pulse.In addition to its use in communication systems, PWM is also used in voltage regulators such as Switched Mode Power Supplies (SMPS) ....etc

pulse position modulation simulink

Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2^M possible required time-shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical communications systems, where there tends to be little or no multipath interference. ....etc
