ABSTRACT:
An electronic ergometer is placed in a housing and comprises a serial arrangement of a transducer to convert the oscillations of the body center of gravity of an individual, implemented as a seismic pickup, and a pulse shaper. Coupled to the pulse shaper is an adjustable high frequency multivibrator with a frequency generating circuit having an element coupled to a unit to select the frequency of the adjustable high frequency multivibrator. Coupled to the output of the adjustable high frequency multivibrator is a frequency divider which, in turn, is coupled to a multi-digit counter connecting an indicator. A zero setting unit is coupled to the reset inputs of the frequency divider and the multi-digit counter.
