1. The problem statement, all variables and given/known data I have an electronics project to design and build a band pass amp for my HNC. The only thing I have been given is it must use a uA741 or TL071 with an input imp greater than 1k and bandwidth between 200hz to 10khz. And gain must be 10db. It is to be used in battery powered equipment. 2. Relevant equations Part of the report write up is that I need to justify my choice of chip and use of either inverting or non-inverting. 3. The attempt at a solution I have decided to use an inverting op amp setup as I can simply put a 1k resistor on the input and that is my input impedance sorted. Also makes calculating the gain easy! I will use the TL071 as the output will not drop off at higher frequencies. The uA741 shows it will drop off at around 10kHz. My problem is we have been taught nothing about a band pass amplifier/filter. So I am unsure if it makes any difference using a inverting/non-inverting setup? I also intend to put a couple of variable resistors in before R1 and R2 to help get the gain as accurate as possible. Any help is appreciated, if I am missing anything obvious could you point me in the right direction? Thanks.
