For People who KNOW how to use QUCS.

that a sine wave has Fourier Coefficients only at it's principal frequency 2. Build an ideal square wave in QUCS and simulate its spectrum. 3. Build a triangular wave in QUCS and simulate its spectrum 4. Solve problem 13-6 and 13-1, verify your analyatical solution with numerical simulation in QUCS. Provide screenshots of relevant simulations for every question. that a sine wave has Fourier Coefficients only at it's principal frequency 2.
