On the other hand, if some fault arises at an electric power amplifying stage PA3, the switch SW is changed to the position shown by the dotted line. Then the voice signal amplified by the amplifier AMP2 is mixed again with the video signal via a hybrid circuit H1. Thus the voice signal receives the amplification of electric power through power amplifiers PA1 and PA2 of the video signal system. As a result, the function of the system is maintained regardless of the fault if the amplifier PA3.

Abstract: PURPOSE:To obtain a synchronous pulse with wide pulse width by comparing the absolute value of output of a low-pass filter with a threshold value, and sampling a pulse from a wide range even when encoded data is inverted in the midway of a period receiving a synchronous word due to a frequency offset. CONSTITUTION:An absolute value circuit 71 finds and outputs the absolute value of output of the low-pass filter A61. A binarization circuit 81 compares the output of the circuit 71 with the threshold value th1, and outputs the pulse which keeps 1 in a period where the output of the circuit 71 exceeds the threshold value th1. The output is inputted to an LPFB 63, and when the LPFB 63 is constituted of a filter of specific moving average length, data is outputted from the filter. A binarization circuit 83 compares the output of the LPF with the threshold value th2, and outputs the pulse which keeps 1 in a period where the output of the LPF 63 exceeds the threshold value th2. Consequently, the synchronous pulse 13 with the synchronous pulse width equal to pulse width length equivalent to the reception period of the synchronous word is outputted from the circuit 83.

Filed: 1990-02-27
Abstract: PURPOSE:To record much audio information by switching duty ratio at a successive recording time and an intermittent recording time with the aid of changing the position of a magnetization inversion part in a control signal. CONSTITUTION:A positive integer multiple video in one frame is intermittently recorded. Simultaneously, in a magnetic recording and reproducing device which executes the successive recording in a prescribed time in the case that an instruction signal is inputted at the intermittent recording time, an output signal is switched to an 'H' level and supplied to a control signal generation circuit 32 by a timing circuit 31 when an alarm signal is inputted to the circuit 31 from an alarm sensor. By changing the position of the magnetization inversion part which is not used for controlling the feeding of a tape at a reproducing time, the duty ratio of the generated control signal is changed to 20% from 60% by the circuit 32. Therefore, only by adding a duty ratio detection circuit 44 to the control signal generation circuit 32 system, alarm recording/ reproducing can be executed. Besides, more audio information is recorded without sacrificing the audio information.
