What is amplitude estimation?
Quantum Amplitude Estimation (QAE)1 is a fundamental quantum algorithm with the potential to achieve a quadratic speedup for many applications that are classically solved through Monte Carlo (MC) simulation.
How do you find the amplitude and phase of a signal?
As for the amplitudes you can get them directly by calculating the peak values of the sine waves. Afterwards you can calculate the phase angle phi= phi2-phi1 and the ratio of the magnitudes between B/A. All you need is to display the waveforms in same diagram.
How do you calculate Hilbert transform?
The Hilbert transforms of f ( x ) = sin x 1 + x 2 computed with our proposed method and MM. Dashed: H f ( x ) = e − 1 − cos x 1 + x 2 ; Solid: the result computed with MM; Dotted: our proposed algorithm.
What is Hilbert transform instantaneous phase?
The Hilbert transform estimates the instantaneous frequency of a signal for monocomponent signals only. A monocomponent signal is described in the time-frequency plane by a single "ridge." The set of monocomponent signals includes single sinusoids and signals like chirps.
