First off I'm a pretty amateur electronics student and I've been trying to design a light organ circuit.
So, I needed to design a circuit that would amplify the voltage out of a filter and because of what we were taught this year I was advised to use a MOSFET.
Because my light organ must accept AC music signals I thought I should use a fixed gain MOSFET amplifier, the circuit diagram is attached.
However the book doesn't seem to give must information about how to calculate Vin and Vout i.e. the gain and how the MOSFET characteristics really come into it (MOSFET is 2N7000)
Could someone please explain how to work everything out?
Thankyou in advance.
