New Unit Improves Resolution by 2000 Times, Enabling Engineers to View RF Signal Instabilities and Transients that They Never Knew Existed BEAVERTON, Ore.—Tektronix, Inc., a leading worldwide provider ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

/ c ± n.m / for n = 0, 1, 2, 3, .... where n is the sideband pair number In this expression, the + indicates the upper sidebands, and the - indicates lower ones ...

Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single frequency counts. Dynamic Spectrum Sharing (DSS) was built to address exactly this, ...

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...

Download this article in PDF format. We also want to recognize Rick Gentile of MathWorks as a co-author of this article. Modulation identification is an important function for an intelligent receiver.

BOs describe the periodic movement of electrons in solids to which an external static electric field is applied. However, it is challenging to measure the BOs directly in natural solids since the ...

IN the radio-frequency spectrum, solar radio bursts have been classified according to their dynamic structure. Information on the velocity of shock waves or the solar corpuscular stream as well as on ...

Kenya has been using analogue radio, which uses either amplitude modulation (AM) or FM. FM is adopted widely because it gives ...
