The blockdiagramofBPSKdemodulatorconsists of a mixer with local oscillator circuit, a bandpass filter, a two-input detector circuit. The diagram is as follows. By recovering the band-limited message signal, with the help of the mixer circuit and the band pass filter, the first stage of demodulation gets completed.

PSK Demodulation (Part 1) - rfcafe
A block diagram for a QPSK modulator is shown in Figure 3. Figure 3. QPSK modulator. PSK Demodulation The demodulation pr ocess can be divided into three major subsections, as shown by Figure 4. First, since the incoming waveform is suppressed car
PSK/QAM/APSK Modem - ComBlock
Modem (modulator + demodulator ) with flexible configuration: Modulation: BPSK, QPSK, OQPSK, p/4 DQPSK, 8-PSK, 16QAM, 16APSK, 32APSK Variable data rates up to 22 Msymbols/s Center frequency: +/- 10 MHz Modulator outputs: Analog baseband differential (2 * 12-bit complex, 64 Msamples/s)
A QPSK demodulator is depicted in block diagram form in Figure 1. π out 2 in parallel-to-serial serial converter carrier φ A/D A/D Figure 1: a QPSK demodulator. This demodulator assumes the original message data stream was split into two streams, A and B, at the transmitter, with each converted to a PSK
Engineering Made Easy: Quadrature Amplitude Modulation
These modulated waves are summed at the output of the transmitter, therefore the final waveform is the combination of both PSK and ASK in digital case or PM and AM for analogue case. Now we will understand this concept with the help of block diagrams of QAM Transmitter and QAM receiver. Block Diagram of QAM Transmitter[PDF]

BPSK - binary phase shift keying D1 - 71 The information about the bit stream is contained in the changes of phase of the transmitted signal. A synchronous demodulator would be sensitive to these phase reversals. The appearance of a BPSK signal in the time domain is shown in Figure 2 (lower trace). The upper trace is the binary message sequence. time[PDF]
3. Pass the recovered carrier phase into the demodulator model where it can be used directly as the reference phase. The computational expense of this approach depends upon the particular modulation format and demodulation algorithm being implemented. In a correlation receiver for 8-PSK, the recov-

The block diagram of Asynchronous FSK detector consists of two band pass filters, two envelope detectors, and a decision circuit. Following is the diagrammatic representation. The FSK signal is passed through the two Band Pass Filters (BPFs), tuned to Space and Mark frequencies.
