BPSK modulator is basically a phase modulator. Here the transmitted signal is a sinusoid of fixed amplitude. It has one fixed phase when the data is at one level and when the data is at the other level, phase is shifted by 180 degree. Binary phase shift keying method has variety of applications in digital communications systems such as the wireless LAN standard, IEEE 802.11, digital modems, wireless telephone networks etc. Differential phase shift keying (DPSK) is an other type of phase shift keying technique which depends on the difference between successive phases. DPSK is significantly simpler to implement than ordinary PSK , since there is no need for the demodulator to have a copy of the reference signal to determine the exact phase of the received signal (it is a non coherent scheme). Here is the practical circuit of BPSK, it is build around CD4016 and 741 Op amp.Also read: Binary Amplitude Shift Keying(BASK) BPSK Circuit Diagram Components Required 1.

Nice explnatn of the circuit..thanks

it doesn’t work properly. because the sin wave and digital binary is not synchronized. the bit duration should be assame as sin wave period and also they should begin and end as same time.

There is no scope of synchronization. It’s only an analog switch.

Wow, fantastic blog layout! How long have you been blogging for?you make blogging look easy. The overall look of yourweb site is wonderful, let alone the content!
Hello,This is nice. do you also have a Demodulator idea/ circuit ?Thank you
