Divides the channel bandwidth into distinct frequency slots (used in analog transmission).
Signals are separated by frequency.
A change in the shape or form of the signal, frequently occurring in composite signals where different frequencies travel at different speeds.

All signal levels are on one side of the time axis (either positive or negative). Return-to-Zero (RZ) schemes drop the signal voltage to zero in the middle of each bit interval to maintain synchronization between sender and receiver. Polar Schemes Voltages live on both sides of the time axis.
Highly susceptible to noise and signal attenuation over long distances. Digital Transmission
