Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

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 ...

Frequency response measurements are a mainstay of RF communications design and generally considered a routine task—unless one of the device ports happens to be at I-Q baseband. Here, the convenience ...
