IEEE 177-1966

New IEEE Standard - Inactive-Withdrawn. The equivalent electric circuit of a piezoelectric vibrator and its parameters are reviewed. The determination of these parameters by the transmission method is described. The method is suitable for frequencies up to about 30 MHz for the commonly encountered ranges of the capacitance ratio r and the figure of merit M, provided that errors due to instrumentation are taken into account. The equations presented in this standard have been formulated to correct these errors.
