Noise in Information - Carrying Channel: Noise in Information-carrying capacity of a channel. This idea will now be explored further, as will means of combating noise. Effects of Noise: That…
High Frequency Limitations: As stated, transistors suffer from High Frequency Limitations. These are of a twofold nature. On the one hand, there are the same difficulties as those encountered with…
Crossed Field Amplifier: The Crossed Field Amplifier is a microwave power amplifier based on the magnetron and looking very much like it. It is a cross between the TWT and…
Triode Equivalent Circuit: Triode Equivalent Circuit - As frequency is raised, vacuum tubes suffer from two general kinds of problems. The first is concerned with interelectrode capacitances and inductances, and…
Cavity Resonators: A cavity resonators is a piece of waveguide closed off at both ends with metallic planes. Where propagation in the longitudinal direction took place in the waveguide, standing…
Antennas in Electronic Communication Articles: Antenna Definition: The Antenna Definition is a quick review of impedance matching (basic transformer theory) and resonant circuits. It was pointed out that maximum power…
Parabolic Antenna: The Parabolic Antenna is a plane curve, defined as the locus of a point which moves so that its distance from another point (called the focus) plus its…
Effects of Antenna Height: At low and medium frequencies, where wavelengths are long, it often becomes imÂpracticable to use an antenna of resonant length. The vertical antennas used at those…
