What is Hilbert analog communication transformation?

When the phase angles of all the positive frequency spectral components of a signal are shifted by (-90°) and the phase angles of all the negative frequency spectral components are shifted by (+90°), then the resulting function of time is known as Hilbert transform of the given signal.

Why Hilbert transform is used in SSB?

The Hilbert Transform finds applications in modulators and demodulators, speech processing, medical imaging, direction of arrival (DOA) measurements, essentially anywhere complex-signal (quadrature) processing simplifies the design.

What is Hilbert transform used for?

The Hilbert transform facilitates the formation of the analytic signal. The analytic signal is useful in the area of communications, particularly in bandpass signal processing.

What is the frequency response of Hilbert transform?

This frequency response has unity magnitude, a phase angle of – π /2 radians for 0 < ω < π , and a phase angle of π /2 radians for – π < ω < 0. A system of this type is commonly referred to as Hilbert transformer or sometimes as 90-degree phase shifter.
