Hey, I am a 2nd yr electrical eng. student, I have a simple low pass filter to convert a square wave to triangular wave.
here is the circuit: (the capactitor and resistor values are not actual... its just for illustrative purpose)
After I have converted it to triangular, I would like to use THIS VERY SAME output voltage to appear across a resistor R2.
but the problem is if i connect the R2 like that as shown ... it will change the the triangular wave shape, because the resistance seen by the capacitor changes.
My question is : Is there any way to ISOLATE the output so that I can use it on the resistor R2 without it affecting the low pass filter ?
