Hellos to all,
A couple of weeks ago, I posted here having problems getting an integrator circuit working. Upon, taking some advise and trying a few things, the problem remains. I have a TL082 op-amp from which I am trying to generate square wave and triangle wave. I have built this up on the breadboard, but I am only getting the square wave. The 100K variable resistor changes the frequency to cover my desired range of the square wave, but the second half of the circuit (the triangle wave) does not work correctly. When I tap in at pin 1 (the triangle output) with headphones, there is a weak noise that does not change with the 100K variable resistor being manipulated. Then, when I remove the 7.16K resistor, there is a seemingly triangle wave at pin 1 that has a very high frequency, is relatively faint, and changes frequency in response to the variable resistor manipulation. I want to be able to tap into the circuit at pin 1 or pin 7 for the two wave forms. I would like each wave to have similar amplitudes, and have the frequency of each vary with manipulation of a variable resistor. The schematic is as posted here:
Oh, thanks for the circuit templates Bill. I am making some progress in diagramming.
