Crystal filter schematic
WebA block diagramme for a practical crystal test set is shown in Fig. 5. Here, the crystal is in series with a small capacitor, and test points are added to allow for measuring the signal … WebEach C-R stage is known as a first-order filter. If a number (n) of such filters are cascaded, the resulting circuit is known as an “nth-order” filter and has a slope, beyond fc of (n x 6 dB)/octave. Figure 3 shows the circuit of a practical 800 Hz phase-shift oscillator that can operate from any DC supply in the 9V to 18V range. To ...
