摘要

Disclosed are a device and a method for comparing a detected frequency signal (first frequency signal) and a second frequency signal which is obtained by delaying the detected frequency, to determine whether the frequency transitioned to a predetermined area on high frequency side or reached a predetermined value on the upward direction side. The frequency detection device (1) comprises: a delayed signal output circuit (11) that outputs a second frequency signal (F2) obtained by delaying the first frequency signal (F1), which has a frequency that changes over time, by a set period (Δi); and a determination circuit (12), which inputs the first frequency signal (F1) and the second frequency signal (F2), determines whether or not the cycle of the first frequency signal (F1) is included in the cycle of the second frequency signal (F2) and/or whether or not the cycle of the second frequency signal (F2) is included in the cycle of the first frequency signal (F1), and outputs a determination signal.
