Short-term HRV including time-domain, frequency-domain analysis .

This paper discuss the location of poles and zeros of network function and its instability,and the frequency-domain analysis of analysis of active RC network,emphasis two-orders low-pass negative-gain circuit,and the transient problem of one-order low pass circuit.

It is pointed out that frequency-domain analysis is a necessary,beneficial and useful complement to time-domain analysis.
