Abstract
Methods and systems for generating a digital representation of the amplitude and phase of a bandpass signal are disclosed. The methods comprise filtering the bandpass signal with a bandpass filter, generating the real and imaginary parts of the complex analytic signal with a quadrature hybrid, determining the amplitude of the complex analytic signal by adding an even power-law transform of the real and imaginary parts of the complex analytic signal, and determining the phase of the complex analytic signal by comparing the real and imaginary parts of the complex analytic signal to zero and comparing an even power-law transform of the real and imaginary parts of the complex analytic signal to each other. Analog to digital converters and methods of converting complex analytic signals to digital signals are also disclosed.
