Bandpass phase shifter and analytic signal generator
Date of Original Version
In this note, a novel tunable bandpass filter/phase shifter implementation (with a Hilbert transformer as a special case) is proposed. The filter can also be used to synthesize a bandpass analytic signal from a real-valued signal. The novelty is the simple, yet elegant implementation that exploits the even and odd symmetry of the in-phase and quadrature carrier modulation.
