摘要:

A circuit is described that enables one to use simple equipment to improve the precision with which the frequency of a driven mechanical vibrator can be measured. The resonance frequency of the system consisting of a mass suspended from a spring is calculated by a procedure that simplifies the application of the general equation which is valid for all masses.
