CONVERTING A SYMMETRICAL INPUT SIGNAL OF A MAGNETIC RESONANCE ARRANGEMENT INTO AN ASYMMETRICAL OUTPUT SIGNAL

摘要

A symmetrical input signal is converted into an asymmetrical output signal. A first conduction path and a second conduction path are arranged parallel to one another based on signal flow. The first conduction path and the second conduction path form a first stage and a second stage. The first conduction path includes a first high-pass element assigned to the first stage. The second conduction path includes a first low-pass element assigned to the first stage. The first conduction path and the second conduction path have a second high-pass element assigned to the second stage. The second conduction path includes a second low-pass element assigned to the second stage and arranged in a chain with the first low-pass element. Each high-pass element shifts the phase of a signal forward, and each low-pass element shifts the phase of a signal backward to generate the asymmetrical signal.
