I don't think they prescribe that for severe head trauma.Cymbalta can help.
please look carefully at the violet trace you will notice the clipping and I have already tried sliding q point up and down but no matter what I do some portion of the negative part is always getting clippedThe scope trace looks normal to me. Clipping would look like a flat segment at the bottom of the negative peak. You don't have to use precisely Vcc/2 for the Q-point. You can adjust it up or down slightly to provide additional margin for either the positive or negative peaks.
Again sir, I already have tried raising the dc supply to 20V, it does nothing,I have tried changing the emitter resistor for different bias voltage also and really it isn't making any difference, actually no matter how or what I do,it isn't making any difference, that's why I changed the transistor from 2n3904 to CL100S but then also nothing! .I kept scratching my head through out the whole day thinking about what is going wrong but could not find any solution that's why I am posting this here to get some expert help like yesterdayYes, well forgive me, but the scope traces in post#28 and post #30 are different and the violet trace was obscured by the cursor. So you either need to reduce the input signal or raise the supply voltage to handle the larger input signal.
I don't know how to interpret what you are telling me, and I have no ready answers. Maybe there is someone with more insight who can help.Again sir, I already have tried raising the dc supply to 20V, it does nothing,I have tried changing the emitter resistor for different bias voltage also and really it isn't making any difference, actually no matter how or what I do,it isn't making any difference, that's why I changed the transistor from 2n3904 to CL100S but then also nothing! .I kept scratching my head through out the whole day thinking about what is going wrong but could not find any solution that's why I am posting this here to get some expert help like yesterday
Question to the OP or to anyone willing to take a look:This is the whole schematics
edit:Op amp used TL-084 and transistor used 2n6292 you need not to worry about the power supply it can provide upto 24V 2A
If you mean the post #1 oscillator, increase the values of the capacitors to, say, 6.8nF.Have you been able to get this actually oscillating as shown? Is this the actual circuit?
I am asking about the oscillator part only
No joy. After checking my .asc against Danko's I realized my simulation has a non-obvious flaw.If you mean the post #1 oscillator, increase the values of the capacitors to, say, 6.8nF.
Thanks Danko; checking yours against my own simulation, found there is a flaw I couldn't catch yet.Full TS's circuit simulation:
