This technique of using I/Q data to represent the modulations of a signal separate to the signal's frequency is known as equivalent baseband signal, supported by the § Narrowband signal model. The data rate of I/Q is largely independent to the frequency of the signal being modulated. See more A sinusoid with modulation can be decomposed into, or synthesized from, two amplitude-modulated sinusoids that are offset in phase by one-quarter cycle (90 degrees or π/2 radians). All three sinusoids have the … See more In an angle modulation application, with carrier frequency f, φ is also a time-variant function, giving: When all three terms above are multiplied by an optional amplitude function, A(t) > 0, the left-hand side of … See more The term alternating current applies to a voltage vs. time function that is sinusoidal with a frequency f.
