beat frequency oscillator वाक्य

उदाहरण वाक्य

1. The beat frequency oscillator was invented in 1901 by Canadian engineer Reginald Fessenden.
2. The audio tone is usually created by use of a beat frequency oscillator.
3. In order to make the carrier pulses audible in the receiver, a beat frequency oscillator is used.
4. Reduction of the carrier level permits higher station to permit demodulation, usually by means of a beat frequency oscillator ( BFO ).
5. Vacuum tubes were used by some of the older technologies popular in the 1960s and 70s, like beat frequency oscillator ( BFO ) detectors.
6. Later airways were based on low / medium frequency ground stations, like the beat frequency oscillator ( BFO ) and the non-directional beacon ( NDB ).
7. The heterodyne oscillator is the ancestor of the " beat frequency oscillator " ( BFO ) which is used to receive radiotelegraphy in communications receivers today.
8. At the receiver, the received signal is mixed with a heterodyne signal from a BFO ( beat frequency oscillator ) to change the radio frequency impulses to sound.
9. Today the heterodyne method is still used to receive CW signals, and the " beat frequency oscillator " ( BFO ) is a standard part of all communications receivers.
10. On reception, the FSK signal is converted to the original tones by mixing the FSK signal with a local oscillator called the BFO or " beat frequency oscillator ".
