Title: Drop out detection circuit
Inventor: HAGIWARA AKIHITO
IPC: G11B20/18
Filed: 1990-02-13
Abstract: PURPOSE:To detect the drop out of a low frequency component in a reproduced FM signal by voltage-comparing the difference signal of the low frequency component of a positive component and a negative component as against the AC center of the reproduced FM signal where two frequency components are overlapped. CONSTITUTION:A video signal where a luminance FM signal and a chrominance FM signal, both of which are reproduced from a recording medium, are overlapped is inputted to a reproduced signal input terminal 1. A rectifier 2 rectifies the positive component viewed from the AC center of the reproduced video signal inputted from the reproduced signal input terminal 1 and a rectifier 3 rectifies the negative component viewed from the AC center of the reproduced video signal inputted from the reproduced signal input terminal 1. The output of a differential amplifier 6 taking the difference between the output of a first low pass filter 4 and the output of a second low pass filter 5 is voltage- compared in a voltage comparator 7. Thus, the drop out of the signal of the low frequency component in the reproduced FM signal is detected.

Title: Data transmitter
Inventor: INAZAKI KENZOU
IPC: H04L12/413
Filed: 1983-02-28
Abstract: PURPOSE:To detect securely whether there is a transmission signal arriving at the input terminal of each data transmitting station from another station or not even when a transmission signal attenuates on a transmission line, by detecting whether a collision between transmission signals occurs on the transmission line or not. CONSTITUTION:For example, the transmission control circuit 3 of a station 10 outputs a transmission command for a data signal which is applied with pulse code modulation (PCM) and addressed to another station at time t1 as shown in the figure (a). A transmitter 4 sends out a data signal having the same waveform with the figure (a) to the transmission line 1 on the basis of the transmission command signal with the slight operation delay of the transmitter 4. Further, the transmission command signal is applied to a delay circuit 8 having a set delay time tau corresponding to the sum of the operation delay time of the trasnsmitter 4 of the station 10 and the operation delay time of a transmit signal detector 11, and this delay circuit 8 applies a signal having the same waveform as the transmit signal from the station 10 as shown in the figure (b) to one input terminal of an exclusive OR gate 9.
