  • Frequency scan and lock circuit for mobile radio channel selection
    Patent number: 3983492
    Abstract: Sequentially received frequency channel samples in a mobile radio telecommunication system are compared by pairs. The name of the channel providing the larger sample in any comparison is overwritten into a storage register if that larger sample is also the newest sequential sample of the pair. The next sample of the sequence is compared to only the larger sample determined in the previous comparison operation. At the end of the sampling sequence the channel name remaining in the register is utilized to tune the mobile unit receiver to the named channel.
