Pcm Tdm Block Diagram. Following is the block diagram of pcm which represents the basic elements of both the transmitter and the receiver sections. The transmitter performs the sampling quantizing and encoding of the signal.
At the receiver side codec receivers serial pcm data and generates anolog signals. O st 2103 tdm pulse code modulation transmitter and receiver trainer. In sampling we are using pam sampler that is pulse amplitude modulation sampler which converts continuous amplitude signal into discrete time continuous signal pam pulses.
Channel 2 is sampled and converted to a pcm code.
Low pass filter this filter eliminates the high frequency components present in the input analog signal which is greater than the highest frequency of the message signal to avoid aliasing of the message signal. Following is the block diagram of pcm which represents the basic elements of both the transmitter and the receiver sections. The technique efficiently utilizes the complete channel for data transmission hence sometimes known as pam tdm. Channel 2 is sampled and converted to a pcm code.
