Title:
SYSTEM AND METHOD FOR PROVIDING THE AMPLITUDE AND PHASE DELAY OF A SINUSOIDAL SIGNAL
Document Type and Number:
WIPO Patent Application WO/2017/212187
Kind Code:
A3
Abstract:
The invention relates to a system and method that provide an amplitude value (A) and a phase delay value (Φ) related to a sinusoidal signal to be measured (s(t)). For this purpose, phase values (ψk) of a reference signal (r(t)), at which the signal to be measured exceeds or falls below the reference signal, are collected and transmitted to a computation unit (3). The computation unit determines the amplitude and delay values from said collected phase values. The system can be produced in a cost-effective manner, in particular using an ASIC circuit or an FPGA circuit.
