The first one represents the transmitter the second one is a linear model of the effects of the channel the third one shows the structure of the receiver. Then D1 is the rectifying diode to make the modulation signal passes through D1 half wave rectifier. If the frequency f is varied proportional to the information signal. 1 In the transmitter the precoder performs level conversion and then encodes the incoming data into groups of bits that modulate an analog carrier. High level modulation low level modulation High level modulation In high power modulation signalthe carrier voltage is modulated at highest power levelthe require power level is obtained by class c power amplifierThe block diagram of high level modulation as shown in figa. Amplitude Modulation AM Frequency Modulation FM and Phase Modulation PM are the examples of Continuous Wave CW modulation while Amplitude Shift Keying ASK Frequency Shift Keying FSK and Phase Shift Keying PSK are examples of Digital Modulation Techniques.
First stage is trans-mitter which contains an optical source bit sequence generator pulse generator and AM modulator.
The carrier generator sends a continuous high-frequency carrier. ASK Modulator It consists of the carrier signal generator the binary sequence from the message signal and the band-limited filter. The predictor circuit is eliminated here and hence no assumed input is given to the demodulator. Figure 63 Circuit diagram of ASK asynchronous detector 2. As shown in the figure binary 1 will be represented by carrier signal with some amplitude while binary 0 will be represented by carrier of zero amplitudeie. 1 In the transmitter the precoder performs level conversion and then encodes the incoming data into groups of bits that modulate an analog carrier.
