Hi I have 3 problems on one of my question sheets, which i am not able to solve partially.
I have uploaded the question sheet & and also what I have worked out so far.
Q62 shows the problem sheet. the three problems are 7,8,9(a).
Regarding 7: I have uploaded what i have done so far in Q623 & Q624 and as you can see they are not correct according to the answers on the problem sheet. Rm should be 100kohm and Rin 275ohm but i get 100250ohm for Rm and 250ohm for Rin.
Regarding 8: I worked out the Current Gain correctly in the box, but I get 0.9999 for the voltage gain and according to the answer on the Problem Sheet it should be 0.9523, I dont know what went wrong.
Regarding 9(a): I have absolutely no clue how to work out the voltage gain for this circuit. I know that the two top resistors form a negative loop but i dont know how to include the bottom resistor and capacitor. Could somebody please tell me how to do this one?? i tried really hard looking up so many books and notes.
thank you very much for your help in advance
