Constant Frequency System
In this system chopping period T is kept constant but the on time Tom is varied. This system is also referred to pulse with modulation or time ration control scheme.
Since we have Vo =Ton /T Vs [from equation by increasing the on time Ton output voltage Vo can be increase. This V0 can be varied between zero and source voltage Vs.
Let the message signal m(t) = α cos (2πf m t) be used to either frequency-modulate or phase- modulate the carrier Ac cos(2πf c t). Find the modulated signal in each case.
