Phase shifter with a reduced influence of errors (original) (raw)

Abstract

The present invention refers to a phase shifter with a reduced influence of errors which measures the phase difference between two signals. According to the invention, the system consists of at least two phase detectors (3, 4) with the wanted signal (1) and the actual signal (2) on their inputs, the respective detectors (3, 4) in a series connected to the respective adaptation circuits of the voltage levels (6, 7) with a pair of signals (8, 9; 10, 11) at their inputs coming from the respective phase detector (3, 4), and an adjustable resistance splitter (16) with a pair of signals (12, 13; 14, 15) coming from the respective adjustment circuits (6, 7) at its input and the wanted or desired signal (17) at its output.
