Hi,I think am understanding this electronics that is all about controlling and shaping of signal such as frequency,amplitude and others and that the basic components of doing this are capacitors and inductors also transistors for switching.Now my question is,HOW DO I CONTROL OR SHAPE THIS SIGNAL with these electronics components in other to build a circuit.PLSSSS CALL MY ATTENTION IF AM WRONG WITH THIS MY UNDERSTANDING AND THINKING.
Shaping and controlling signals is not always a MUST when dealing with electronics.
Know your goal before dealing with pulse shaping. There are many applications which don't require pulse shaping - moreover keeping a pulse at a steady level before proceeding any further.
Basically you can do almost everything in electronics. The outcome depends on knowledge and common sense almost equally.
