Introduction to Semiconductor Materials and Devices: An electronic device controls the movement of electrons. The study of electronic devices requires a basic understanding of the relationship between electrons and the…
Principles of Communication Systems: In a broad sense, the term Principles of Communication Systems refers to the sending, receiving and processing of information by electronic means. Communications started with wire…
CCIF Intermodulation Distortion: In the second method of carrying out an CCIF Intermodulation Distortion test, the two test signals used have equal amplitude, and relatively high but slightly different frequencies.…
Selectivity Measurement Receiver: The Selectivity Measurement Receiver is its ability to reject, (adjacent) unwanted signals. It is expressed as a curve, such as the one in Fig. 16.5, which shows…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
Op Amp Comparator Circuit: Op Amp Comparator Circuit - In the opamp applications discussed so far, the amplifiers use negative feedback. Under normal conditions, when negative feedback is used in…
Signal Conditioning System: Signal Conditioning System - The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first stage…
Measurements of Thickness using Beta Gauge: Beta Gauge - A common and characteristic feature of a radioactive element is that they disintegrate spontaneously to produce fresh radioactive elements called daughter…
