Double Stub Matching: If a transmission-line matching device is to be useful in a range of different matching situations, it must have as many variable parameters, or degrees of freedom, as the standing-wave pattern. Since…
Smith Chart for Transmission Line: The various properties of transmission lines may be represented graphically on any of a large number of charts. The most useful representations are those that give the impedance relations along…
Reactance Properties of Transmission Lines: Reactance Properties of Transmission Lines : Just as a suitable piece of transmission line may be used as a transformer, so other chosen transmission-line configurations may be used as series…
Quarter Wavelength Transmission Line: Sections of transmission lines that are exactly a Quarter Wavelength Transmission Line or Half Wavelength Transmission Line long have important impedance-transforming properties, and are often used for this purpose at radio…
Standing Waves in Transmission Lines: Standing Waves in Transmission Lines : When power is applied to a transmission line by a generator, a voltage and a current appear whose values depend on the characteristic impedance…
Losses in Transmission Lines: Types of Losses in Transmission Lines are three ways in which energy, applied to a transmission line, may become dissipated before reaching the load: radiation, conductor heating and dielectric heating. Radiation…
Fundamentals of Transmission Lines: Fundamentals of Transmission Lines (in the context of this book) are considered to be impedance-matching circuits designed to deliver power (RF) from the transmitter to the antenna, and maximum signal from the…
Receiver Types: There are Two Receiver Types namely, Pilot Carrier Receiver and a Suppressed Carrier Receiver; the suppressed carrier receiver incorporates a frequency synthesizer for extra stability and also is used to show how ISB…
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 all other forms of AM.…
Stereo FM Multiplex Reception: Assuming there have been no losses or distortion in transmission, the demodulator output in a Stereo FM Multiplex Reception, tuned to a stereo transmission, will be exactly as shown in Figure…
