The bipolar transistor has several disadvantages: it has low input impedance because of forward biased emitter junction, it has small…
By placing two PN junctions together we can create a bipolar junction transistor. In a PNP transistor the majority charger…
Multiplexers and demultiplexers are devices that route signals. A multiplexer also called a data selector takes one of several inputs…
Power electronics deals with the applications of solid state electronics for the control and conversion of electric power. The conversion…
An instrument may be calibrated by comparing its reading with that of a more accurate instrument when both are measuring…
The figure below shows two dc ammeters connected in series, so that they are both measuring the same current. Figure: …
Most of the water treatment plants in the previous decade were manually operated. However, they were automated to a certain…
An analog controller typically employs op-amps to provide the necessary gain and signal processing. Let’s consider the flow control system…
A tuned amplifier operates over a band of frequencies centered on a resonant frequency. Its two main requirements are to…
