Circuit arrangement for reducing effective output of stabilized d.c. supply using controlled discharge of series capacitor

Supply voltage disconnection method e.g. for gas discharge lamp or dimmer, has monitoring voltage source switched to current source at current threshold after load switching in for providing disconnection signal

Signal evaluation circuit for AC or DC signals for environmental measurement applications using operational amplifiers for precision rectification of AC signals

Method for reducing signal levels of e.g. universal mobile telecommunications system service, involves acquiring any radio services simultaneously within baseband frequency range, and attenuating signal levels of radio services

Isotropic magnetic field sensor comprises coils with magnetic cores, where coil is positioned cross-wise on magnetic core in x-axis and y-axis with distance in magnitude of coil diameter

Method for contactless determination of local power and flow direction in telephone line or line combination in integrated network, involves immediately/centrally comparing phase determined by magnetic field measurement and reference phase

For analog differentiation of pulsed high frequency signals with lower pulse frequencies, divides the signals into a path to study only positive flanks and a path only for negative flanks
