This is the high level block diagram for a communications system. Data is generated externally and passed to the transmitter (Tx), which sends the data across some medium (Channel) to be received at the receiver (Rx). The received data is compared against the sent data for bit errors.

Click one of the blocks to show its output waveform and settings.
