Delayed Sweep Oscilloscope: Many oscilloscopes of laboratory quality include a delayed sweep feature. Delayed Sweep Oscilloscope feature increases the versatility of the instrument by making it possible to magnify a selected portion of an undelayed…
Delayed Automatic Gain Control: Delayed Automatic Gain Control: Simple AGC is clearly an improvement on no AGC at all, in that the gain of the receiver is reduced for strong signals. Unfortunately, as Figures 6-14…
Delay Line in Triggered Sweep Circuit: Figure 7.13 shows a Delay Line in Triggered Sweep Circuit. Figure 7.14 indicates the amplitude of the signal wrt time and the relative position of the sweep generator output…
Definition of Recorder: Definition of Recorder - A recorder is a measuring instrument that displays a time-varying signal in a form easy to examine, even after the original signal has ceased to exist. Recorders generally provide…
Definition of Laplace Transform: The Definition of Laplace Transform is used to solve differential equations and corresponding initial and final value problems. Laplace transforms are widely used in engineering, particularly when the driving function has…
Definition of Laplace Transform: Here we are going to discuss one of such transform methods called Laplace Transform Method which transforms the time domain differential equations to the frequency domain. To understand the philosophy of…
Definition of Inductance of Transmission Line: The formula for definition of inductance of transmission line is as follows: Voltage induced in a circuit is given by where ψ represents the flux linkages of the circuit…
Definite Distance Type Impedance Relay: Fig. 21.21 shows the schematic arrangement of a Definite Distance Type Impedance Relay. It consists of a pivoted beam F and two electromagnets energized respectively by a current and voltage…
Define Suppression of Carrier: Three main systems are employed for the generation of SSB; the filter method, the phase cancellation method and the "third method." They differ from one another in the way of suppressing…
Define Permanent Magnet in Magnetic Circuits: Define of Permanent Magnet is an important excitation source (life long) commonly employed for imparting energy to magnetic circuits used in rotating machines and other types of electromechanical devices.…
