Circuit diagram:
Kindly refer the previous paper. I don't remember the diagram. You can give me marks for the theory part.
Explanation:
As can be seen from the diagram in my predecessor's answer sheet, the circuit looks rather ugly( I remember bits of the diagram, though..). I mean, those stupid looking triangles with those silly straight lines next to them (our lecturer calls them diodes, I don't know why) look rather out of place. Here's one of those......don't you think its ugly too..?
And those spring like things (inductors, i believe they are called) marked L1 and L2 look really disgusting. But I think those zig zag lines look rather cool...they are called...eh....can't remember......ah! resistors! that's right....they are called resistors. That's it for the description.
Working:
Now comes the tough part. The device is supposed to be a frequency modulator, so i guessed it is supposed to do a considerable amount of frequency modulating, in addition to its other duties. But I really don't understand how the damn thing does any frequency modulating at all. But my BCE lecturer told me it does a lot of frequency modulating and it is supposed to do quite a good job of it too, and so, i took her word for it. So, whoever you are, correcting this paper, i'd like you to trust me and take my word for it too. I know you'll find this hard to believe, but that top half of the circuit has something to do with providing a positive output, and the bottom half, a negative output. Bloody brilliant, I'd say. Splendid job, old chap!, I'd say that too. But alas! I can't say how it manages to do so, for I have absolutely no idea about it....and I'm out of patience, can't think of any more crap for this answer. You are at liberty to give me whatever marks you think this answer deserves, but do consider that my answer is completely original, still to be published in any book. Thank you for patiently reading this answer....
