US 2001/0054935 A1 · Process for reducing the decay and transient times of oscillating circuits

Abstract

In the previously known processes, the oscillating circuit amplitude decays exponentially after the excitation voltage has been interrupted. Upon switching the excitation voltage on again, the oscillation first has to be built up. This reduces the data transmission rate of transmission plants which are operated by intermittently working oscillating circuits. With the new process, both the current and the voltage can be held at their maximum values when the excitation voltage is interrupted. This eliminates the decay of the oscillating circuit amplitudes. When the excitation voltage is switched on again, the oscillating circuit can continue oscillating at its maximum amplitude without delay. The data transmission rate is increased because the decay or starting times are eliminated.
