Hi, New to the forum and glad to be here.
My project: I built a very known Contactless Telephone Line Ringer Detector circuit and it works as designed but, I want to benefit two fold by spliting the DC and AC signals out and have my Micro-controller control a relay based on the state of AC and DC at any given time. If I place an uninsulated alligator clip on the insulated vinyl jacket phone line this device detects the -48volts vdc for ON HOOK.
How would I split the AC to one ciruit and DC to another circuit ? (Separate the AC and DC telephone Signals for use in other circuits)
Thanks, Bobby
Here is what I have so far:
