The range required is max of 50'
Noise can be RF welders, motors etc..
The current solution has a frquency of 300MHZ i believe.
There is no PC or USB present. The transmitter is oviously a hand held gizmo and the receiver is powered by 24V and the output basically closes a 24V relay coil
Anyone have a good source for a wireless transmitter/receiver package.
We have been using an off the shelf set for one of our products at work from Linear Corp. This one is similar to a really old garage door opener technology.
We have been having problems with range and interference...

I do not really care about super exact calculations, I know roughly what the times are from experimentations. I am just trying to come up with a general formula for V(t)
across the cap.
Berkeman, this is not a homework question, but part of a design for a circuit I am doing at work.
I understand all of the above mentioned, I was tryin to isolate my problem area.
I am trying to come up with an equation to determine how long it will take to charge the capacitor up to a...
I am trying to figure out how to come up with an equation to calculate the voltage
across a capacitor for an RC circuit that is supplied by a chopped / full-wave rectified ac waveform shown below.
The shaded portion is the actual input signal to the RC circuit.
anybody have any ideas ?
