Title: Signal detecting circuit
Inventor: NAGASE NORIO
IPC: H04L25/02
Filed: 1990-11-19
Abstract: PURPOSE:To make it possible to detect the presence or absence of inputting of an input digital signal using a simple signal detecting circuit by providing the detecting circuit with the function that when a signal is input, level 'L' is output by detecting the average value and comparing input voltages, and that when no signal is input, the detecting output is set at 'H' by the 'H' level side out of two system inputs. CONSTITUTION:Since in a period of time of the presence of a input signal, both two system inputs have AC waves that voltage level varies between level 'L' and level 'H' at a clock cycle, the output voltage of the average value detecting section 22 takes a medium value between 'H' and 'L'. Here, reference voltage Vref is set at greater than this medium value, transistors Q5 and Q6 are both OFF, and current I4 flows to the Q7 side, so the reference voltage is fixed at the detected output of V0=Vcc-I4R6-Vbe and becomes 'L' level. On the other hand, when no input signal is present, one, (e.g.; input A) from two system inputs is fixed at 'H' level, and the other (input B) at 'L' level, and the average output at the A side becomes 'L' level and the other side becomes 'H' level, and further transistor Q6 is turned ON and transistor Q7 is turned OFF. Accordingly, the detected output becomes V0=Vcc-Vbe, thereby fixing the detected output at 'H' level.
