Limits of communication systems
Noise in Communication
Noise is a general term which is used to describe the random and unwanted
signals which affect a wanted signal and carry no information.

Modulation
Modulation is the process of moving a low-frequency signal to a high-frequency
and then transmitted the high-frequency signal. Generally the low-frequency
signal carrying the original infor
Pulse Analog Modulation : Pulse Amplitude Modulation (PAM)
Pulse-amplitude modulation (PAM), is the simplest form of analog pulse
modulation. PAM is a form of signal modulation where the message infor

Delta Modulation (DM)
PCM is a very complex technique. Other techniques have been developed to reduce the
complexity of PCM. The simplest is delta modulation (DM). PCM finds the value of the signal
