WebDec 15, 2024 · The AM modulation is simply done by multiplying the waveform with a carrier generated by one of the instrument's oscillators. The following figure shows the most straightforward AM method, i.e. double-sideband (DSB) modulation [1] which can be easily carried out using the UHFAWG by changing its mode from 'plain' to 'modulation'. Fig. 1. WebSSB - OVERVIEW In DSB, the spectrum has two side-bands around the carrier frequency. The Upper Side Band (USB) and Lower Side Band (LSB) have even amplitude and odd phase symmetry. Because of this symmetry, transmission of both sidebands is not necessary. By transmitting one sideband then we save half the bandwidth. To benefit from this there is … how to carding amazon
