Frequency domain plots for filtered Square and Sawtooth waveforms. Cn, Dn(dBV) &nversus harmonic number plots Plot in two graphs Cn, Dn(dBV) &n(degrees) for n = 0 to 10. Square wave 50% duty cycle with 1stand 3rdorder low pass filters with different cutoff frequencies fc Trigonometric Fourier Coefficients Magnitude Cn (dBV) versus Square wave. Sawtooth 50% symmetry with 1stand 3rdorder low pass filter Trigonometric Fourier Coefficients Magnitude Cn (dBV) versus Square wave
