Title: Privacy telephone set of communication circuit
Inventor: MUTOU MASAHARU
IPC: H04K1/04
Filed: 1982-10-12
Abstract: PURPOSE:To attain the inversion of a voice spectram and normalized smooth switching by modulating a voice signal to one of the 2nd or 3rd subcarrier or both subcarriers alternately, passing one of upper and lower side waves by a filter then modulating the passed signal alternately by said subcarriers or one or both alternately. CONSTITUTION:A voice signal fa is modulated by the 2nd subcarrier 4fp to generate a modulated signal (4fp+ or -fa). A BPF6 passes only the signal (4fp+fa) and a switch 13 applies a carrier 4fp and the 3rd subcarrier 5fp alternately to obtain output signals fa, (fp-fa), which are applied to a modulated signal transmitting circuit 8 together with a synchronizing signal fs to transmit the modulated signal. A receiving signal detecting circuit 17 receives the transmitted signal and outputs a signal fa'. The signal fa' passes a demodulated signal obtained by switching the carriers 5fp, 4fp by a switch 28 through a BPF by using any one of (fp-fa) or fa to select only the demodulated signal (4fp+fa). The carrier 4fp is added to the selected signal, an output signal fa is taken out and supplied to an amplifier circuit 20 and then the amplified signal is outputted from a speaker 22.
