WebThe FM waveform is generated by applying the formula given above. The integral of sin (x) is –cos (x) + C. The constant C is not relevant here, so we can use the following equation to compute the FM signal: xF M (t) = sin((10 × 106 × 2πt)− cos(1 × 106 × 2πt)) x F M ( t) = sin ( ( 10 × 10 6 × 2 π t) − cos ( 1 × 10 6 × 2 π t)) WebA signal is Pulse Code modulated to convert its analog information into a binary sequence, i.e., 1s and 0s. The output of a Pulse Code Modulation (PCM) will resemble a binary sequence. The following figure shows an example of PCM output with respect to instantaneous values of a given sine wave.

WebFM transmitter is the whole unit which takes the audio signal as an input and delivers FM modulated waves to the antenna as an output to be transmitted. FM transmitter consists of 6 main stages. They are illustrated in the following figure. The working of FM transmitter can be explained as follows. WebThis block diagram of FM receiver is similar to the block diagram of AM receiver. The two blocks Amplitude limiter and De-emphasis network are included before and after FM demodulator. The operation of the remaining blocks is the same as that of AM receiver. We know that in FM modulation, the amplitude of FM wave remains constant.
