Abstract: A method and system for improved detection of analog signals, where the analog signals may be composed of one or more analog frequencies. In the method and system, an analog signal is received. A stream of data samples is created from the analog signal. Based on the stream of data samples, a confidence factor regarding the presence of the one or more analog signals is created. The confidence factor is created based upon a confidence factor calculated for each of the one or more analog frequency signals. The confidence factor calculated for each of the one or more analog frequency signals is calculated utilizing incremental energies associated with each of the one or more analog frequency signals.

Abstract: Selection of a program in a DAB receiver is facilitated. There are provided a data table 31 containing sets of a service ID and a time data indicating a broadcast time of that program in order of the time as well as a data table 32 containing the service ID in order of receiving frequency of that program. When an operation for selecting a program is performed, it is checked whether or not a data coincident with a service ID of a program of the latest broadcast time among data of the data table 31 is found in the data table 32. As a result of this check, if it is found, a program of that service ID is selected. As a result of the check, if it is not found, the same processing is thereafter repeated to select a program, with a service ID of a program of the next latest broadcast time among data of the data table 31.

Abstract: A radio receiver comprises an RF tuner (10) on a computer card (11) having a frequency selector (19) for determining the current selected frequency. A programmed computer functions as a control system 100 controlling the tuner and a display screen 200 presents data and user selectable inputs to the user. An input peripheral device (101) enables the user to input data or information and commands to the control system. The control system causes a display (220) display on the display screen (200) in real time both digital and analogue indications of the current frequency being passed by the tuner (10); and provides a tuner frequency select control responsive to input of a frequency change command by the user to change the current selected frequency.
