Abstract
Inventia se refera la un dispozitiv afisor pentru comanda sintetizorului si comutarea gamelor de frecvente ale unui radiogoniometru, dispozitiv care realizeaza selectarea si afisarea pe display a frecventelor radiogonometrate în granule I (200...599,9 KHz) sau II (1,6...3,5999 MHz), comanda sintetizorului radiogoniometrlui si comutarea electronica a gamelor I/II, functie de frecventa. Ungenerator de clock 1, încarca, prin niste comutatoare K1...KV, niste numaratoare 2, 3, 4, 5, 6, starea acestora fiind afisata pe niste elemente de afisare 12, 13, 14, 15, 16. Sintetizorul radiogoniometrului este comandat în cod complementar fata de 9 de niste blocuri 17, 18, 19, 20, 21. Un circuit multiplexelor 22 si un bloc de interfata 23 comuta gamele I/II. Inventia se poate aplica în echipamentele electronice la care se înscriu prin tastatura informatii digitale sau la care se doreste separarea unor domenii de lucru (radiogoniometre, sintetizoare de frecventa, aparate de masura si control etc.).The invention relates to a display device for commanding the synthesizer and switching the frequency ranges of a radiogonometer, a device which selects and displays on the display the radiogonometric frequencies in granules I (200 ... 599.9 KHz) or II (1.6. .3,5999 MHz), the radio goniometer synthesizer command and electronic I / II range switching, depending on the frequency. Clock clock unloader 1 loads K1 ... KV switches with counts 2, 3, 4, 5, 6, their status being displayed on some display elements 12, 13, 14, 15, 16. The radiogonometer synthesizer is ordered in complementary code to 9 of blocks 17, 18, 19, 20, 21. A multiplex circuit 22 and an interface block 23 switch the I / II ranges. The invention can be applied in electronic equipment that are entered through the digital information keypad or in which the separation of some working fields (radio-goniometers, frequency synthesizers, measuring and control devices, etc.) is desired.
