Abstract

PURPOSE:To prevent the deterioration in S/N due to crosstalk by eliminating a call end signal component and a control signal included in a sound signal by a filter device to prevent sound malfunction because of the call end signal component. CONSTITUTION:The filter device 4 is connected between a preamplifier 3 and a selective calling device 5 and consists of a notch filter or an HPF. The call end signal component included in a sound signal of an output (b) of a tape reproducing device 2 is eliminated by the filter 4 and broadcast by radio. On the other hand, a calling device 16 to be selected by a slave station 14 eliminates the call end signal from the sound signal, then the slave station 14 keeps stable broadcast. Further, even if a crosstalk phenomenon occurs at the output (b), the crosstalk is eliminated in the filter 4 after passing through the device 3 by making a continuous tone signal frequency of the output (a) the same as the call end signal frequency, and the clear communication with improved S/N and without crosstalk is attained.

, the tape playback device (2) operates, and the t voice signal of the CB channel output (b) is transmitted via the preamplifier (3) to the ``C loudspeaker'' (3) and directly to the trumpet speaker (9). Along with the loudspeaker broadcast, the selective calling device Jit (5
), transmitting device (6), transmitting antenna qq to slave station (1
4) It will be broadcast on radio. At this time, a continuous tone signal of the A channel output (a) is output to detect the non-operation of the tape playback device (2), and the broadcast control device (
7) Smell °C is broadcast while the CA channel output (a) is present, and a control output (C) is output to stop broadcasting when the A channel output (a) disappears. Preamplifier 1 (:l), selective calling device (5), transmitter (6)
The broadcasting state continues as long as there is a control output (C) from the broadcast control device (7), and the broadcasting is stopped when the control output (c) is cut off. Tape playback *@(
The end-of-call signal component included in the audio signal of the B channel output (b) from 2) is removed by the filter bk (4) to the transmitting device (6) and the transmitting antenna. Unrelated broadcast to C slave station α via aCt.jL
Ru. In the case of child σ4, the slave station (b) can continue a stable broadcasting state without end-of-call malfunction because the end-of-call signal component is removed from the audio signal of the selected calling device (ue) of C1. . In addition, due to the crosstalk phenomenon in which the continuous tone signal of the A channel output < a) in the tape Niusou @ (2) wraps around the audio signal of the B channel output (b) and worsens the sound, C records on the A channel output. By making the continuous tone signal frequency the same as the final tone color 8' frequency, a crosstalk phenomenon occurs in the B channel output (b).
After passing through, install the filter! 1 (4), amplification device (8), trumpet speaker (
Even when the amplification number is directly transmitted by 9), C is also transmitted from the selective calling device (5), the transmitting device (6), and the transmitting antenna QQ to the slave station (141).
Filter device (4) I removes the crosstalk sound and ensures clear speech with good S/N ratio.
