Question

Name the circuit(s) that you will use to :
1. convert DC in pulses (Hint: not AC just pulses)
2. vary frequency of pulses
3. vary amplitude of pulses

Answer 1

1. chopper
2. u can vary frequency by controlling duty ratio of the chopper
3. u can vary amplitude based on the chopper configuration used.

Answer 2

hey, if you are good at microcontroller, you can have any kind of PULSES or variations according to current, bt it needs programming skills. all the best!!
