We need modulation to multiply the signal message by the carrier and prepare it for sending and demodulation. Many modulation techniques exist for converting the analog signal to digital signal. Transmitting digital signal over any medium is safer and economical. One technique is pulse time modulation that is the technique that encodes the signal into axes of digital signal. In some radios this modulation technique is used. This kind of modulation is analogues to delta modulation. The types of time modulation are pulse width modulation, and pulse duration modulation.
