The catv charge and control system is mainly composed of the management software 、 the header data modulator and the terminal charge and control equipment. i am responsible for design catv charge and control equipment and test system. the header data modulator is used to encrypt the control single from computer and transmit it into the appointed frequency. the terminal charge and control equipment demodulate out the control single from data modulator and transmit it to the addressing control part, where the demodulated fsk single is received and well - handled by the cpu unit, decode the unauthorized signals and deliver it to the shut point, shut point make use of capability of wideband anf characteristic of shut, then the signal of illegal customer will be turn off and vice versa, the legal customer can receive the normal signal

There are many ways of modulating signal about bpsk such as castas loop, square loop, etc. usually the carrier wave is put forward firstly, then the purified carrier wave is used to demodulate the output data ( all these things are usually completed in the same loop ). these methods have their strong points but at same times, it is difficult to design and achieve these ways
