switch circuit design
hi guys
I have this problem, where I need to design a transistor switch to switch on and off the sinusoidal waves from the wein bridge oscillator. so the switch should be triggered by a microprocessor, i.e. the microprocessor sends signal to switch on the switch, if no signal is sent to the switch, then the oscillator is turned off.
What im asking here is the switch circuit (not included the microprocessor part), and i take it uses a comparator to compare the voltage from the microprocessor then it switches the oscillator.
find attached the oscillator that should be edited to include the switch, and the dereised output signal waveform (shouldnt be exactly like what i drew, but is just to give an idea).
Hoping to see you help.
