Abstract :
A transformation is given which enables crystals of equal motional inductance to be used in unbalanced semi-lattice filters which specify different inductance values. Allowance is made for stray capacitance between the crystal electrodes and earth; this capacitance is especially significant for metal-encapsulated units.
