pwm 12v
Hi,
I'm trying to convert a pulsed 12V signal into a constant 12V signal.
The circuit pulses several times a second so very quick.
Can you tell me what sized capacitors, resistors i'd need to do the job?
I was going to run the cap/resistor in parallel to flick a relay coil. to switch 12v line from a 12v battery.

pulse to cap to resistor to coil
cap and resistor, coil grounded on other end
looking at all the voltages/wattages on maplins website and none of it makes sence.
Please help.
