EQs come in all shapes and sizes, but the basic concepts are the same: take a signal with one distribution of frequencies, and output a signal with boosted or cut energy at certain points in the ...
Introduction – Because of their typically fast edge rates, crystal oscillators can generate a large number of high-order harmonics. Figure 1 indicates a generalized trapezoidal digital signal. The ...
Quartz crystals have the property that their amplitude/phase characteristic repeats itself at frequencies that are an uneven multiple of the fundamental frequency. There are so-called overtone ...
