Title: Monitoring circuit for bidirectional signal
Inventor: OTANI HIROMICHI
IPC: G06F21/62
Filed: 1986-11-05
Abstract: PURPOSE:To reduce signal loss due to the insertion of a monitoring circuit with a simple structure, by constituting a circuit in such way that a directional coupler is inserted to a single cable to be monitored, and the monitoring circuit is inserted to the directional coupler. CONSTITUTION:At a signal detecting point in the single cable by which a signal is to be detected, an input terminal 41 is connected to an output terminal 42, and one directional coupler 4 is inserted to the cable. A part of a high frequency signal inputted to the terminal 41 passes through a resistance attenuator 1a via a branch output terminal 43, and is inputted from the high-pass filter side of a directional filter 3, and is outputted from the common terminal of the filter 3, and arrives at a monitoring terminal 2, then it is monitored. Meanwhile, a large part of a high-pass signal inputted from the terminal 41 is transmitted to a load connected to the terminal 42, however, an impedance unmatching part with the load is reflected, and a part of it passes from a balance resistance terminating terminal 44 to a resistance attenuator 16, and is inputted to a low- pass filter side in the filter 3, then, it is attenuated. Therefore, few of output is issued to the terminal 2, and also, neither reflected wave component arrives at the terminal 2.
