Digital transmission is the transmission of binary electrical or light pulses in that it only has two possible states, a 1 or a 0. The most commonly encountered voltage levels range from a low of +3/-3 to a high of +24/-24 volts. Digital signals are usually sent over wire of no more than a few thousand feet in length.
Digital Data/Analog Signals Must convert digital data to analog signal. One such device is a modem to translate between bit-serial and modulated carrier signals. To send digital data using analog technology, the sender generates a carrier signal at some continuous tone (e.g. 1-2 kHz in phone circuits) that looks like a sine wave. The following techniques are used to encode digital data into analog signals (Fig 2-18) Resulting bandwidth is centered on the carrier frequency. amplitude-shift modulation (keying): vary the amplitude (e.g. voltage) of the signal. Used to transmit digital data over optical ber. frequency-shift modulation: two (or more tones) are used, which are near the carrier frequency.
