WebThe first crystal is called the polarizer. It serves the function of polarizing the light. The second crystal is called the analyzer. When the crystal axis of the analyzer is at right angles to that of the polarizer, no light passes through the analyzer. See Fig. 4. A polariscope can also be made from two sheets of Polaroid. Malus’s law. WebA sharp cutoff lowpass filter (LPF) or bandpass filter ( BPF) could be used to attenuate the image. fIF = fRF –fLO Case 2. RF frequency is higher than LO frequency. This places the image frequency 2 x fIF below the RF frequency – now inband for a LPF.

WebThe aging of narrow and intermediate band crystal filters is almost solely dependent upon the aging of the crystals themselves. Thus, after proper conditioning, it is possible for the filters to age no more than a fraction of a part-per-million per year. This makes crystal filters ideally suited for phase-matched applications. http://n5dux.com/ham/files/pdf/NorCal%2040A%20-%20PPTs/322Lecture13.pdf
