Hi all. I'm currently writing a report on a tuned transistor circuit. I'm supposed to find a Q value for it but I'm a tad overwhelmed. My lecturers splurged out a heap of formula in my direction. I can't make any sense of it. From what I understand, I should be able to find the Q factor from my maxiumum gain value. Somewhere along the line impedence comes into it. This is what I'm told: "From the measurements made determine measured values for the gain at resonance (Go) and the quality (Q) of the circuit. Using your value of Q calculate the impedance ZO of the tuned collector circuit at resonance using the relation ZO = Q ?0 L, given that L is 1.12 mH. Use your value of the circuit voltage gain at resonance (Go) to calculate the transistor transconductance gm" It's all very confusing. Can anyone clear it up for me? I think I'm doing some stuff back to front. Thanks.
