One of the most important classes of time dependent signals are periodic signals. Periodic signals satisfy tho following signal equations, x(t) X(t) x(t+nt) for n 2,3. The periodic signals to be observed in this laboratory assignment are shown below. In all the examples A represents the amplitude of the signal and may be given as the measurement from 0 to the peak value A, Apk or can be given as the measurement between A and -A which defines a peak-to-peak...
1. KDP A typical electro-optic amplitude modulator is shown above. A linearly polarized beam with wavelength 2 633nm is sent a KDP crystal which is oriented such that when a voltage is applied across its faces the index of refraction along y-axis and x-axis make an angle of 45 degrees with respect to the input polarization. This results in a phase change between the x and y components of the input beam. For KDP, the electro-optic coefficient is given as...
