A voltage across the capacitor when the 555 timer IC is reset indicates a time interval corresponding to the start and stop signals.Muhammad Taher Abuelma'Atti
A narrowband MEMS direction finding sensor has been developed based on the mechanically coupled ears of the Ormia Ochracea fly. The sensor consists of two wings coupled at the middle and attached to a substrate using two legs. The sensor operates at its
A clean insulation acts as a capacitor. The current should lead the voltage by 90 degrees in a pure capacitor. The pure insulation should also conduct similarly. If the insulation is deteriorated, the current will also have resistive factor. This will cause the angle of the current to be les...
The phase shifter 49 consists of a pair of capacitors 51, 53, and a pair of resistors 55, 57. Each capacitor 51, 53 is connected in series with one of the resistors 55, 57. Potentiometers 59, 61 are respectively connected across the capacitor 51, resistor 55 and capacitor 53, resistor...
The signal of FIG. 6B is generated when the tracking position of pickup device 3 is moved in a reverse or inward direction across the previously scanned tracks on disc 1. Differentiating circuit 47 produces signals corresponding to the points denoted by the X marks. The signals from differentia...

Dynamic range of a differential pixel is enhanced by injecting, synchronously or asynchronously, a fixed compensating offset (ΔV) into a differential signal capacitor whenever magnitude of the differential signal across the capacitor exceeds a predetermined value. The number (N) of ΔV offsets made...
Connected across them are two diodes in series. Connected to the junction between the diodes is an ohmic resistance (R) connected to earth. A constant d.c. voltage can be applied and the branch connection exchanged between input and output to find the fault, by measuring the current flow....
