Title: Transmission of tonal signal for fully double communication
Inventor: OGASAWARA HIROMICHI
IPC: H04N1/32
Filed: 1985-02-18
Abstract: PURPOSE:To reduce less the generation of noises within a reception signal band by transmitting a tonal signal whose amplitude is increased gradually from zero and then attenuated gradually down to zero after the amplitude reaches a certain level and kept at a fixed level. CONSTITUTION:The ternary (-V, O and +V) amplitude control pulse signal S1 is supplied to a Miller integration circuit 1 from a control terminal CNT, and a trapezoidal base band signal S2 is delivered. This signal S2 is modulated into a signal S4 of a rectangular wave via a modulation circuit 2 by a carrier clock signal S3 which drives an analog switch SW with the same frequency as a atonal signal. The DC component of the signal S4 is eliminated by a capaci tor C2 and the signal S4 is converted into a signal S5. The high frequency compo nent of the signal S5 is eliminated by a low pass filter 3 and the signal S5 is converted into an output signal, i.e., a tonal signal S6 and delivered through an output terminal OUT. This output signal S6 has a small side band wave component compared with a conventional one. Furthermore the frequency spec trum of the signal S6 is concentrated at a place near a carrier frequency.
