hey all. i've started this project to do with a filter amplifier. All i know is that the input is AC and the output is DC amplified by 5.6 times the input. Thats it! i have no idea how the AC is converted to DC. i kno it has somethn to do with the capacitors and diodes, but i jus cant figure out how they do it!! cd sumone pls help me?? And is pin 3 grounded?? This is an inverting amplifier, right??
