Frequency Modulation (FM) is a widely used modulation technique in various communication systems due to its advantages of improved noise immunity and better signal quality compared to Amplitude Modulation (AM). FM signals are characterized by var…
Frequency Modulation (FM) is a widely used modulation technique in modern communication systems due to its superior noise immunity and improved signal quality compared to amplitude modulation (AM). FM signals are widely used in applications such as…
SSB(Supressed Sideband) demodulation is the process of recovering message signal from the SSB modulated wave. SSB is also called SSB-SC where SC means suppressed carrier as the carrier signal in the SSB signal is completely removed. Here we illustra…
AM demodulation is the process of extracting message signal from the AM modulated wave received by AM receiver. The AM modulated wave is generated using AM modulator circuit at the AM transmitter. The AM signal can be either standard AM (also calle…
AM demodulation is the process of recovering message signal from incoming AM modulated wave. There are two ways to demodulate AM signal- (1) square law detector and (2) envelope detector. The square law detector uses non-linear devices such as tran…
In electronics communication system, modulation and demodulation are processes that embeds message signal into carrier signal at the transmitter and extracts message signal from the received signal at the receiver. Because we can embed information …
Amplitude Modulation (AM) is a method of transmitting information by varying the amplitude of a carrier wave in proportion to the message signal. However, in order to recover the original information from the received AM signal, we need to demod…
Beat Frequency Oscillator(BFO) is an electronic oscillator used in the radio receiver to generate audio frequency signal. The incoming RF signal such as continuous wave Morse code signal or single side band(SSB) AM signal are mixed with the signal …
Here AM radio communication system simulation is illustrated in Proteus. The radio communication system is designed using the MC1496 balanced modulator demodulator. In the demonstration, a message tone signal and AM modulated and sent from the tra…
This is a tutorial on how the AM Detector Demodulator with MC1496 works and how to build it. AM detector(demodulator) is a circuit that translates AM signals to baseband signal by mixing the AM signal with local oscillator signal. This is done to re…
