Second, we need to synchronize the digital transitions with the carrier waveform. With these improvements, we could design the system such that the 180° phase change occurs when the carrier signal is at (or very near) the zero-crossing.

Normally EPM based networks do not use every channel included into their full RF range, but only a portion, called the hop set. These hop sets need not be that large to be effective. ribby hall soft playWebSpread Spectrum Modulation. A collective class of signaling techniques are employed before transmitting a signal to provide a secure communication, known as the Spread Spectrum Modulation. The main advantage of spread spectrum communication technique is to prevent “interference” whether it is intentional or unintentional. redheads ship yard
