Polar NRZ-L, NRZ-I, RZ schemes

Polar NRZ-L, NRZ-I, RZ schemes. The voltages are on the both sides of the time axis NRZ-L (Non Return to Zero-Level): The level of the voltage determines the value of the bit NRZ-I (Non Return to Zero-Invert): If the bit is 0 there is no change; if the bit is 1 there is a change
