Abstract
The inductors in a switched resonant circuit are alternately connected in make before break fashion to ensure that at least one inductor is always connected to the tank circuit. This avoids switching discontinuities caused by signal propagation delay. By connecting both coils together between individual coil reading cycles, transients are absorbed.
