Abstract :
A formula for determining the time-constants of thermoelectric effects in thermal converters from FRDC-DC transfer difference measurements versus reversing frequency is derived. The influence of higher-frequency harmonics in the FRDC-waveform is calculated for shunt capacitances in the heater/range-resistor combination.
