FR2748873A1 - Radio receiver with digital automatic frequency selection and display - Google Patents

Abstract

The receiver contains a digital selector (g1,g2) and an automatic frequency sensor (A) with an LCD (2). A keypad (g) selects the frequencies for memory and is controlled by a switch which is moved between memory open and memory closed positions. The frequencies are displayed with the names of stations if required. A paper listing can also be produced. The link (1) between the radio receiver and the sensor and the link (4) between the keypad and the receiver are radio remote controlled. The link (3) between the sensor and the amplifier is partly integrated into the sensor while that (4) from the digital selector to the amplifier is partly integrated with the selector.

Description

 The present invention relates to a system for automatic reception in digital accuracy of radio frequency waves in their entirety existing and transmitted to the listener according to each of its geographic positions, supplemented by a digital precision selection system by the accuracy of radio values systematically within its reach.

 Reception of radio broadcasts is still carried out very traditionally, above all by a selection method that is clearly accentuated blindly.

 The analog display requires the listener to carry out almost hazardous research work using a rotary selection mode to pick up his radio broadcast for a moment.

 The LCD display, a progress well noted compared to the analog display, still requires the listener almost exactly the same type of traditional effort for a research work to capture his desired radio broadcast of a moment, by mode digital, or, selection.

 The progress made in the LCD display is this digital display accuracy of each radio frequency value of each frequency / station. But the selective mode is still carried out almost randomly although a little more precise by the LCD display mode.

The affictaee allows a more targeted, more precise and more real selection mode. The selection
tion is then carried out in the digital accuracy of each hertzian value of each frequency / station of the LCD display, this is the progress made in this selective field being effected by this type of digital research and by scanner; Despite this, selective chance still remains the main drawback.

Selection by memorization is proof that there is any drawback
difficult to remedy. Selection with the RDS system consisting in displaying the rrAn of the station and the corresponding radio frequency. The automatic reception system according to the invention is to leave, in a certain way, optional the display of the name of the station; Hence the importance of documentation D
Documentation D, according to the invention, is the solution to remedy a handicap of the listener in his insapid search task by selective mode always hazardous and tiresome.

The automatic reception system according to the invention is the solution contributing to material
read a tool still non-existent in practical and current use available to the auditor in the technical field of daily telecommunications: The Auto-Sensor-Frequency.

 A tool that is worth two, since it essentially consists of two main elements: The Auto-Display LCD Dial and the Digital Selector.

The Auto-Display LCD Dial, according to the invention, is the technical solution to make matt
in the Auto-Sensor-Frequency by being the constituent. The LCD Auto-Display Dial assigns itself the role of automatically displaying all the existing radio frequencies transmitted on one of the three or three columns of its LCD screen at each of the different positions.
auditor's geographic information. The Auto-Display Dial overcomes the drawbacks still represented in the traditional analog and LCD display which has been replaced.

 The Digital Selector #, according to the invention, is the solution overcoming the difficulties of any selective mode where the search is most often carried out blindly and randomly. It consists of a numeric keypad from 0 to 9 with. , making it possible to dial directly and digitally the wireless value of the station to be selected, with a validation key (d), either to validate a simple instant listening independent of any memorization, or for a simultaneous memorization with a memory-selection keys #, and an LCD screen # displaying the frequency and the station selected for listening. It therefore replaces any traditional random and random selective mode, by rotation, digital research and even scanner.

 The documentation #, according to the invention is represented in the form of a list containing the names of the stations and their corresponding frequency; n represents almost the paper equivalent of the LCD Auto-Display Dial that once the Auto-Sensor-Frequency # is running, lists on its LCD screen automatically the stations and corresponding frequencies that the documentation # completes, when the display of the station name is optional.

 The automatic reception system according to the invention is the solution contributing to materializing a tool still nonexistent in the practical and current use of the listener and at his disposal in the technical field of radiophonic telecommunications on a daily basis.

- Auto-Capteur-Fréquentiel #, consisting of two main elements: The Ca
dran Auto-Display # and the Digital Selector # (can be integrated or not
in #), which are both, according to the invention, the technical solution
to make material in the Auto-Sensor-Frequency which is the Main Cons
titrant of the automatic reception system according to the invention.

The automatic reception system according to the invention is broken down into four main elements
- The Auto-Sensor-Frequency
- The Radio Receiver Station (isolated in its element)
- The sound amplifier: Headphones, loudspeaker, speaker, cabinet.

- The documentation #
This represents, in a way, the decomposition of the Radiophonic Receiver Station as a whole where the Radiophonic Receiver Station is isolated in its element, like the atom isolated from the molecule.

The autaratic reception system, according to the invention, is capable of being made up of five possible connections in this breakdown of the radio reception station as a whole:
# Connection from the Auto-Sensor-Frequency to the Radiophoni Receiver Station
that ==) The Radio Receiver Rate is thus isolated in its element, detached
one from the other (Auto-Sensor-Frequency and Radio Receiver Rate), the
praier by having become a "Radiophnic Remote Control".
