摘要： A frequency measuring means comprising a network having input means for receiving a signal which is to have its frequency measured and output means delivering signals transmitted therethrough, said network providing a signal transfer characteristic which is a function of frequency for the range of frequencies to be measured, first means deriving signals reflected from the input means of said network, second means deriving from the output means signals transmitted by said network, and third means receiving and comparing signals from said first and second means for providing an indication of the frequency of a signal delivered to the input of the network.
