Editing Communications system (section)

=== Receiver ===
Once the signal has passed through the communication channel, it must be effectively captured by a receiver.  The goal of the receiver is to capture and reconstruct the signal before it passed through the transmitter (i.e. the A/D converter, modulator and encoder).  This is done by passing the "received" signal through another circuit containing the following components:
# Noise Filter
# [[Digital-to-analog converter]]
# Decoder
# Demodulator
# Signal Amplifier
Most likely the signal will have lost some of its energy after having passed through the communication channel or medium. The signal can be boosted by passing it through a signal amplifier. When the analog signal converted into digital signal.
