- 4. A radio receiver according to claim 3 wherein said frequency data is stored in said memory as a function of N, further comprising circuit means responsive to said memory and connected to said frequency divider for communicating a value of N to said frequency divider selected in accordance with said broadcasting station identification data and said broadcasting time data, whereby said 1/N output is adjusted in accordance with said broadcasting station identification data and said broadcasting time data.
- 5. A radio receiver comprising:
- phase locked loop means for generating an output oscillation signal;
- means responsive to the output oscillation signal for receiving and frequency-converting a radio broadcast;
- a memory having a data table including broadcasting station name identification data for a plurality of broadcasting stations, wherein each of said stations broadcasts at a group of different time periods over different respective frequencies, and said data able further includes predetermined broadcasting time data corresponding to each of said programs, and predetermined frequency data corresponding to said different time periods for receiving a predetermined radio broadcast at a predetermined broadcasting time period;
- a random access memory for containing data identifying a broadcasting station;
- a timer for generating current time data;
- a first key means for selecting one of said plurality of broadcasting stations by name and additional key means for selecting a broadcasting station; wherein; and
- processing means connected to said phase-locked loop, to said memory, to said random access memory, and to said timer, so that in response to operation of said first key means selecting a broadcasting station name and said current time data said processing means reads out frequency data corresponding to said selected broadcasting station from said data table, the frequency data being supplied to said phase locked loop means, whereby based on said selection of said broadcasting station by name, the radio receiver is automatically tuned to a one of said group of different frequencies at which said selected station broadcasts at said current time, and
- in response to operation of said additional key means, the data identifying said broadcasting station is read from said random access memory, the data read from said random access memory and said current time data are employed to extract frequency data corresponding to said identified broadcasting station from said data table, and the frequency data thus extracted is supplied to said phase locked loop means, whereby a predetermined frequency at which said identified station broadcasts at said current time is selected.
- 6. A radio receiver according to claim 5 wherein said additional key means comprises a station key and an enter key, said station key and said enter key being employed together to write said data indicating said broadcasting station in said random access memory and said station key being thereafter employed to read said data indicating said broadcasting station from said random access memory.
- 7. A radio receiver according to claim 5 further comprising display means for displaying the current time data, the name of the selected broadcasting station, beginning and ending times of a current or subsequent broadcast of said selected broadcasting station, said predetermined frequency, and an indication whether said radio receiver is now receiving said radio broadcast or is on standby to receive said radio broadcast.
- 8. A radio receiver according to claim 5 wherein said means for receiving and frequency-converting a broadcast signal includes a channel selection tuner and said phase locked loop means comprises a voltage-controlled oscillator for producing said output oscillation signal, a frequency divider connected to said processing means for dividing said output oscillation signal by N to produce a 1/N output, where N is one of a plurality of predetermined numbers corresponding to a respective one of said group of different frequencies in said data table, a reference oscillation circuit for producing a reference oscillation signal, a phase comparing circuit responsive to the 1/N output and the reference oscillation signal for producing a comparison signal, and a low-pass filter responsive to the comparison signal for producing a voltage signal, said voltage-controlled oscillator adjusting the frequency of said output oscillation signal in response to said voltage signal and said channel selection tuner selecting a channel in response to said voltage signal.
- 9. A radio receiver according to claim 8 wherein said frequency data is stored in said memory as a function of N, further comprising circuit means responsive to said memory and connected to said frequency divider for communicating a value of N to said frequency divider selected in accordance with said broadcasting station identification data and said broadcasting time data, whereby said 1/N output is adjusted in accordance with said broadcasting station identification data and said broadcasting time data.
