What I am asking is a design or pulse shaping question. We learn about analyzing circuits but not designing them in school. Let's say I have a input signal which is a triangular wave and I want to generate some output signal with some sophisticated shape that are not simple sin or square wave or something we know. How should we design the circuit inbetween to achieve that? What I can think of is to write equation of my output signal of desire in time domain somehow and take laplace of it to figure out what components in what order should be placed to achieve this signal.
