hi guys, i have been given a very simple opamp circuit to build, i have built it and it works perfectly. all it does is amplify a signal, and the variable resistor VR1 with value 1 mega ohm acts as volume control.
i have to write a report on this circuit, i know how the opamp itself works, but im a bit unsure on what the capacitors are for and a couple of the resistors.
could anyone please explain to me what the function of C1, C2, C3, C4, C5, R3 R4 are. i think its something to do with filtering of DC or hum from mains or something but not sure.
im new at electronics an this is my first ever project. any help is very much appreciated
thanks
