A first inverter logic element, a second inverter logic element, and a third inverter logic element constitute a loop circuit, and a first transistor, a second transistor, and a third transistor are connected between an output of the third inverter logic element and an input of the first inverter logic element. An output signal is taken out from an output of the second inverter logic element, and an oscillation frequency is regulated by the first transistor, the second transistor and the third transistor. Consequently, in a voltage controlled oscillator of the present invention, the number of loop circuits and transistors for regulating the oscillation frequency can be decreased, so that a simulation process can be simplified and required characteristics of the oscillation frequency can be easily obtained.

A load cell produces an oscillating signal indicative of the weight of the product. The maximum and minimum values of the oscillating signal are determined to provide a reference value which is an average of the maximum and minimum values. Using the reference value for the starting point and ending point, one cycle of the oscillating signal is identified and integrated to determine the corresponding weight of the product. The apparatus compensates for errors in the relationship between the actual starting and ending points of the cycle and the reference value.
