WebMar 14, 2016 · Beam alignment depends on CCD real-time image analysis and processing. In order to improve the quality of the alignment, multiple filters are used in far-field and near-field image processings. WebThe normal filter is easy, just align the IF to the crystal frequency. This may not be exactly the published frequency, however, this is the practical frequency to use, and it should not be far off. If the crystal doesn t work, dismantle it and clean with alcohol, or get another one. A sweep generator is also helpful here.

Webhumidity, etc., in which the crystal filter has to operate. The number of crystal units is dictated by a desired filter order, because each crystal unit is characterized by one complex pole (see Fig. 2). Therefore, the filter with N crystals is often referred to as a filter with N poles. Parallel capacitances, denoted as C0 in Fig. 1, reduce the
Webcrystal pairs to further define the passband and steepness of the skirt. A disadvantage of the single crystal filter when peaked at maximum selectivity is that it may tend to ‘ring’ or ‘echo’, making it difficult to copy weak CW signals – effects caused by the crystal oscillating for a short period after being excited by the signal.
