A drive section that applies an AC signal to an unknown load, a detection section that detects load current and load voltage, a filter section that extracts a specific frequency component from the detected load current and load voltage signals, and this filter. In the impedance analysis device, the filter section includes a converter section that rectifies an output signal of the converter and then A/D converts it, and a controller section that analyzes the digital signal output from the converter section. Bandpass・
It consists of a filter, a clock source that generates a clock signal, and a frequency divider that varies the frequency of the clock signal from this clock source. An impedance analysis device characterized by changing the center frequency.
