I am currently working on designs for a project that involves splitting a signal 2 ways depending on the state of a sensor. I have been thinking of using gates, e.g. a NOT gate then an AND gate for 1, and for 2 just an AND gate.
BUT here is my problem my sensor is current sink only (up to 40mA 15 volts dc) but for the gates to work do i not need a positive input? i was thinking of using an opto-coupler
the frequency of the signal to be split will be between 0 and 475Hz
i wold prefer a delay time of less than 32 ms( over the hole cercit ) 16 wold be optimum
