ok thanks yep the in put is less than 500hz.
am thinking of using farchild AND gates a well as inwerters
https://www.electro-tech-online.com/custompdfs/2007/11/ZC4081.pdf
was not thinking wen sagested opto curlers
it wold be used for running 2 of these off of each out put signal
**broken link removed**
or 1 of these off each output
**broken link removed**
or similar the signal in these doesn't have to be out of sink
the input signal may look like this**broken link removed**
the frequency will be...
i have rightly cocked that up
**broken link removed**
this is what I think i wanted to draw before I had a phat stress at my telecommunications provider and go to angry to think properly
SENSOR 1 =
LOOK AT THE *.GIF FILE
Duh *hits self in head
quad 2 in NAND gate is a simple 1 IC solution as demonstrated here this shold work am i correct? **broken link removed** EDIT:
no it wont will it
but this will **broken link removed**
ok soty for the mis-drawn digram it was about 1 am here the amlatude of the incoming signal is 11~15V pulsed dc eg 0v +13v 0v +13v.... can be reduced by resistors ect.
So in summary al i want I want to achieve is a logic gate with the following truth-table
Input output
A B...
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...
