Abstract:
A free channel selector for selecting from a plurality of channels an optimal channel for establishing radio communication, each of which channels may be selected by a radio frequency (RF) module for outputting signals carried on that channel, the free channel selector comprising:a peak detector electrically connectable for receiving signals output from the RF module and for generating, for each of the plurality of channels, a first signal indicative of the strength of the signals transmitted on the respective channel;means for generating, for each of the plurality of channels, a second signal indicative of the respective channel;memory means electrically connected for receiving first and second signals from the peak detector and the generating means, respectively, the memory means having an array of cells for storing first and second values representative of the first and second signals, respectively, for each of the plurality of channels so that the first and second values are stored in association with one another;means electrically connected to the memory means for selecting one of the stored first values corresponding to a desired signal strength;means electrically connected to the selecting means and the memory means for determining the second value stored in association with the selected one of the stored first values; andmeans electrically connected to the memory means and to the determining means for identifying the channel indicated by the determined second value, the identified channel being the free channel.
