Hello,
I have a function generator to generate a sinusoidal voltage waveform (+5-5 V) and a coil. I have to design a circuit that allows to change AMPLITUDE and FREQUENCY of the current flowing in the coil. To amplify current I have a transistor (MJE) (both pnp and npn). How should I design the circuit?
I'm using LTspice as simulator.
Thank you
Marc
