Abstract: PURPOSE:To remove a difference frequency component, to eliminate the need for the trap of a filter, and to improve reliability, by setting phase differences between signals 40fN and signals fSC inputted to two converters to 90 deg. and summing up two outputs. CONSTITUTION:A signal switching circuit 11 switches four signals 40fN from a 1/4 frequency dividing circuit 2 to output two 90 deg. out-of-phase signals 40fN. The output of an oscillator 6 is supplied to a converter 14 and also delayed in phase by 90 deg. through a 90 deg. phase shifting circuit 16 to be supplied to a converter 7. The two converter outputs are summed up at a part 15 to remove a difference frequency component while leaving a sum frequency component because the signal 40fN lags the input to the converter 7 by 90 deg. and the signal fSC leads it by 90 deg.. Therefore, almost no spurious component appears at the output of the adder 15 and the trap of a BPF8 is unnecessary. Therefore, the cost is reduced and the performance is improved.

Abstract: PURPOSE:To continuously receive only formal terminal of which procedure is finished by previously sending a next key which becomes effective in a fixed term to a tariff prepayment terminal, canceling a former key with the aid of timer output and writing a new key in a decoder. CONSTITUTION:When a timer 18 automatically generates an off-signal at the end of a month or the beginning of a month and stops sending an cipher key K2 to the decoding part 12, the decoding part 12 can not decode. Therefore a cipher key K3 cannot be obtained and both of an image and a voice cannot be decoded. On the other hand, the ciphered information on a next month pay ment, the key K2 and time information are simultaneously sent with a terminal address to the terminal in which the next month tariff is paid for until a fixed date from a center. Thus after passing the fixed term, the tariff non-payment terminal automatically cannot decode the cipher.
