When the level of the FM modulation signal is sufficiently high in the signal selection circuit 4, the FM modulation signal directly inputted from the broad band amplifier 1 is selected by a level detection output of a level detector 2 and fed to a PLL detector 5, in which the signal is...
Examples of an FM detector circuit include a circuit using a Foster-Seeley method, a circuit using a ratio method, a circuit using a PLL method, a circuit using a slope detection method, and a circuit using a discriminator detection method. Japanese Unexamined Patent Application Publication No....

Another disadvantage of performing phase detection using one of those PFDs is that they are quite noisy, and require a charge pump with a relatively narrow low-pass filter (or integrator) because the phase correction pulses to the charge pump may occur at very low frequencies. The frequency det...
If one sub-carrier is significantly stronger than others, spectral leakage might prevent correct detection on adjacent channels. To prevent this, channels can be separated, but then the total number of available sub-channels decreases. Otherwise, pulse shaping can be applied on the transmitter side...
