would be the one I would look at, sorry for wasting your time previously. I'm not really asking for all the working to be done for me, merely an understanding of what I'm doing, apologies if it comes across that way

sorry now I see that you said MFB topology but I was on holiday and only had a chnace to look at it closely today

I'm not quite getting what you're saying? According to my notes (and reading back up) I can't see why this isn't a bandpass filter up until about an hour ago when NascentOxygen said it wasn't?

Because that was my chosen design, looking online and at my notes I thought this was Sallen & key

ermm that would be yes, damn.

Berkeman, this was the one I thought was the most appropriate as it is very briefly shown in my notes as a bandpss filter with no other explanations. I got the bandwidth of 1.5kHz by dividing the fo/Q. this gives the upper and lower corner frequencies I used the value of R1 as 3.3Kohm which...

Homework Statement Homework EquationsThe Attempt at a Solution I worked out the Bandwidth at: 1500Hz so therefore Fh should be 4050Hz and Fl should be 2550Hz Could someone give me any tips as to how correct my key is? with respect to the Bode plot on the sinusoidal output of my design the...

Homework Statement When testing the circuit of FIGURE 1 (a) it was found that the output shown in FIGURE 1 (b) was obtained when the input was connected to ground. explain why this was so and attempt an estimate of the capacitance values of C.Homework EquationsThe Attempt at a Solution...

definitely me. I had a silly moment, sorry, don't know why I had it in my head that the Sinusoidal (big, massive clue there) was a DC input. I've designed a new circuit so that I'm able to get a square wave, and a capacitance wave, just struggling to get the harmonics right for the sawtooth

There won't be input waveforms from the DC sources would there? Sorry if I'm way off the mark but this question really has me confused

Yeah that's what I'm struggling with but thanks anyway :)

good spot thanks! Also, i did think making the alternate sources negative but that does not seem to afftect the output so I think my design may be wrong that's why I was considering a capacitor to store the voltage until it gets to 5 then disperse to form the correct wave form as shown in the...

Homework Statement Homework Equations See above in the question The Attempt at a Solution I know that I need to be using a summing amp with the sinusoidal terms but I am struggling to calculate the input values that I need, also I think I need a capacitor in place of R6 but I'm not...
