sum frequency मीनिंग इन हिंदी

उदाहरण वाक्य

1. When you multiply sine functions you will get a sum frequency and a difference frequency.
2. The lowpass filters pass the difference ( i . e . baseband ) frequency while rejecting the sum frequency image, resulting in a complex baseband representation of the original signal.
3. There are two processes that are commonly used to achieve the conversion : second harmonic generation ( "'SHG "', also called frequency doubling ), or sum frequency generation which sums two non-similar frequencies.
4. A signal broadcast at 100 MHz ( the wanted signal ), and mixed with the 110 MHz LO will create the sum frequency of 210 MHz ( ignored by the receiver ), and the difference frequency at the desired 10 MHz.
5. However, a signal broadcast at 120 MHz ( the unwanted signal ), and mixed with the 110 MHz LO will create a sum frequency of 230 MHz ( ignored by the receiver ), and the difference frequency also at 10 MHz.
6. One application is spectral inversion, typically of speech; a carrier frequency is chosen to be above the highest speech frequencies ( which are low-pass filtered at, say, 3 kHz, for a carrier of perhaps 3.3 kHz ), and the sum frequencies from the modulator are removed by more low-pass filtering.
7. The tensor elements can be determined by using two different polarizers, one for the electric field vector perpendicular to the plane of incidence, labeled S, and one for the electric field vector parallel to the plane of incidence, labeled P . Four combinations are sufficient : PPP, SSP, SPS, PSS, with the letters listed in decreasing frequency, so the first is for the sum frequency, the second is for the visible beam, and the last is for the infrared beam.
