Title: Circuit for detecting output interruption
Inventor: SUZUKI KATSUO
IPC: H04J3/14
Filed: 1987-02-19
Abstract: PURPOSE:To prevent mis-transmission of an output interruption alarm caused by the effect of a reflecting wave by adding an input signal and a signal level subjected to phase shift by [(2n+1)/4] wavelength through a phase shift means by means of an adder means and comparing the result with a reference value at a comparison means. CONSTITUTION:The titled circuit is provided with the phase shift means 5 shifting the phase of the input signal by [(2n+1)/4] (n is 0, 1, 2,...), the adder means 6 adding signal levels across the phase shift means 5, and the comparator means 7 comparing the output of the adder means 6 with a reference value and outputting the result of comparison. That is, since a voltage at a point parted by lambdag/4 from a point with a zero standing wave given shows Vmax, the levels across the phase shift means 5 shifting the phase of the signal by the [(2n+1)/4] wavelength are added by the adder means 6 and the comparator means 7 compares the added value with the reference value. Thus, even when one of them is cancelled and the level goes to 0, the level at the point subject to phase shift by the [(2n+1)/4] wavelength is maximized. Thus, the possibility of mix-transmission of output interruption alarm caused by the effect of a reflected wave is improved.
