I have to use a function generator and oscilloscope to find the critical frequency which I believe is the same as cutoff frequency(the 0.707 bit)

I have to draw the frequency response curve.

I think I know how to do this. my lecturer is off sick so I haven't been able to get any help though I have found some things on the internet.

so far, I make the circuit. connect the function generator across the input. then channel 1 of osc to input, channel 2 of osc to output and connect the ground to ground of circuit.

this way I have an input waveform and an output waveform. I think the voltage remains the same at 1volt. I think I have to increase the frequency and measure the output voltage. I should be able to see the difference in voltage between the two wave forms?

im not sure about this. I emailed my lecturer but I think he may be a little too ill as I have no answer.

after this I have to construct an op amp circuit. input resistor is to negative and 10k, the feedback resistor is 100k. it has two 15v supplies.

I have to, measure and record the gain and bandwidth of the amp. draw the frequency curve.

change the value of the feedback resistor to give a gain of -100

measure and record the gain and bandwidth of the amp, draw frequency curve and comment on results of both.

compare the results of both virtual and practical aspects of this assignment in terms of ease or measurement, errors and accuracy of results.

I will be using excel to show a response curve using graph.

I think I may be correct in the testing of the filter, the op amp im not to sure about. I don't know how to measure the bandwidth. I don't know how to work a function generator that well either. it only goes to about 1v. we have power supplies at college.

any help would really be appreciated!!!!

thanks
