Current Limit Control of Drives: Current Limit Control of Drives scheme of Fig. 3.3 is employed to limit the converter and motor current below a safe limit during transient operations.…
Basic Radar System Block Diagram: Basic Radar System Block Diagram consists of a transmitter and a receiver, each connected to a directional antenna. The transmitter is capable of sending out…
Interconnection of Data Circuits: In the United States, a recent FCC ruling, in part 68 of the Rules and Regulations, permits for the first time non-telephone company interconnection to telephone…
Pulse Communication Articles: Measurement of Information in Communication System: Having said what information is not (it is not meaning), we now state specifically what information is. Accordingly, information is defined…
Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the…
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…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances.…
Reflection of Electromagnetic Waves by a Conducting Surface: In view of the way in which signals propagate in waveguides, it is now necessary to consider what happens to Reflection of…
