Frequency Spectrum of the Rectangular, Triangular and Trapezoidal Signal

EMC problems usually occur at higher frequencies than the highest internal frequency. The reason for this is that any arbitrary signal can be composed of many single sinusoidal signals. Thus, a 20MHZ clock signal may cause problems at 100MHz. This video first shows how the frequency spectrum of a rectangular signal, triangular signal and trapezoidal signal looks mathematically. Afterwards, the determined formula is explained and proven in the laboratory.
