Title: Sound signal controller
Inventor: ISOBE TAKASHI
IPC: H04B1/10
Filed: 1992-04-08
Abstract: PURPOSE:To attain sound indication in a stable state by cutting off a high frequency component of a sound signal through the decreased channel separation when an electric field strength of the sound signal is high and external noise is frequently inputted and keeping the control while external noises last. CONSTITUTION:A noise detection circuit 6 detects multi-path noise and it is integrated by an integration circuit 10. A short circuit 9 is open when the integration value is lower than a threshold level to inhibit channel separation and high frequency component elimination in a stereo broadcast. Upon the receipt of noise on the other hand, a short circuit 8 is closed to connect other terminals of registers 12, 14 to ground thereby reducing outputs of SNC and HCC signals from output terminals 11B, 11C. When the noises last for a prescribed time, an output of the integration circuit 10 exceeds a threshold level of the short circuit 9, which is closed and a voltage of the SNC and HCC signals from the output terminals 11NB, 11C. Thus, a multiplexer circuit 4 decreases the separation and cuts off the high frequency component.

Here, an inspecting line 3 having a resistance circuit 8 is connected across terminals C and A which are not grounded. Then, the reactive component Igc which is 180 deg. out of phase with respect to a voltage Eca across the terminals and an inspecting current Ir in the reverse direction flow through the inspecting line 3. The inspecting line 3 is arranged along a class-2 grounding line 2 so that the current Ir flows in the reverse direction with respect to the current Io. The synthesized current A1=Io+Ir of both currents is measured with a clamp meter 4. The magnitude of the current Ir is adjusted with the circuit 8. The value when the current A1 becomes the minimum value is measured as the effective component Igr. Since it is not necessary to open the grounding line, working can be performed safely.
