If a similar technique is applied to digital signals, the output will be amplitude, frequency or phase shifts (where each shift is a transition from 0 to 1 and 1 to 0). In analogue communication, we change the radio carrierР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s amplitude (AM), frequency (FM) or phase (PM) in response to the input signal. How do we transmit a bit stream?Р В РІР‚СњР В РІР‚С› bit stream is just a signal with transitions from LOW to HIGH voltage levels instead of continuous variations.

In the next section, we will talk about how to modulate these bit streams so they can be transmitted over radio waves. This is amplified and fed into a loudspeaker.Р В РІР‚СњР вЂ™Р’Вigital communications taking place between computersР В РІР‚СњР вЂ™Р’Вigital communication over radio include digital television broadcasts (DVB-S2, ISDB etc.), digital radio (DAB etc.), GPS systems and mobile phone communication. The signal is amplified and demodulation extracts the superimposed voice signal from the carrier.

The modulated radio frequency signal is amplified and delivered to the station antenna for transmission.Р В РІР‚СњР В РІР‚С›t the receiver the radio wave is picked by the receiver antenna and converted back to the radio frequency signal. For this Frequency Modulation (FM) or Amplitude modulation (AM) is used. This signal is amplified and passed to the modulator where it is superimposed onto a radio frequency carrier. The microphone converts the voice into a continuously varying electrical signal.

Moving on from this topic, in this article we will discuss digital communication and digital modulation techniques and how they are used to transport non-continuous signals such as binary or serial data. Various techniques such as AM, FM and PM were discussed. Thus the voice signal is recovered, amplified and can be fed to a loudspeaker. Analogue modulation takes a continuously varying signal such as voice signal and superimposes it onto a radio frequency carrier and demodulation at the receiver separates and extracts the signal. In another article, Analogue modulation, we talked about analogue communication systems.
