Methods for the measurement of frequency and equivalent resistance of unwanted resonances of filter crystal units — 12 стр.
Describes two methods for the measurement of frequency and intensity of unwanted responses of filter crystal units. Both methods are based on the use of a measuring bridge in which balancing of the parallel capacitance is performed at a frequency removed from the main or any unwanted resonance. Has the status of a technical report.
