Uses of Ground Wave Propagation: Uses of Ground Wave Propagation along the surface of the earth and, as previously mentioned, must be vertically polarised to prevent short circuiting the electric…
Fundamentals of Electromagnetic Waves: Fundamentals of Electromagnetic Waves are energy propagated through free space at the velocity of light, which is approximately 300 meters per microsecond. As the object travelled downward,…
Two Hole Directional Coupler: It is often necessary to measure the power being delivered to load or an antenna through a transmission line. This is often done by a sampling…
Product Demodulator: The Product Demodulator (or detector), as shown in Figure 6-44, is virtually a mixer with audio output. It is popular for SSB, but is equally capable of demodulating…
Theory of Frequency Modulation and Phase Modulation: Frequency Modulation and Phase Modulation is a system in which the amplitude of the modulated carrier is kept constant, while its frequency and…
Extensions of Single Sideband Amplitude Modulation: The Extensions of Single Sideband Amplitude Modulation is namely, Forms of Amplitude Modulation: This section on amplitude modulation defines, describes and lists the main applications…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Sensors and Transducers: The definition of Sensors and Transducers are follows, The input quantity for most instrumentation systems is nonelectrical. In order to use electrical methods and techniques for measurement, the…
