What is the difference between a Doppler radar and a regular radar?

Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.


Can anyone explain the M effect of HBC or HRC fuses?

M effect stands for 'Metcalf' effect after the person who discovered it. It involves the use of a small amount of low-melting point alloy (often solder) fixed to the fuse element (wire or strip). Under low overload conditions the fuse element heats up causing the M-effect alloy to diffuse into the metal of the element, increasing its resistance and hence shortening the time to blow compared to the same element without M-effect. Under high overload conditions the fuse element heats up so quickly that there is no time for diffusion to occur. Surprisingly, fuse designers use this effect as a way of creating a fuse with time-delaycharacteristic, because it allows them to use a thicker wire (or strip) than they would otherwise be able to for a given current rating. It is this thicker material that allows a time-delay fuse to withstand short-duration high- current surges.


Why is MOSFET called IGFET?

MOSFET is Metal Oxide Semiconductor Field Effect Transistor. IGFET Insulated Gate Field Effect Transistor. But these expressions are practically synonyms.


What is meant by proximity effect in transmission line?

Assume the AC currents are going in opposite (SAME) directions in a twin pair transmission line. The magnetic fields so created have the effect of forcing the current flow towards the centre (OUTSIDE). The effect is greater with higher frequency. As the copper is not being effectively utilised, the resistance goes up. This effect is distinct from "skin effect". The effect is also greatest if the gap between wires is small. Unfortunately, as of April 2009 an on-line calculator is difficult to find.

Explain about the effect of the time constant RC in envelope detector?

The circuit that generates signal having the shape like imaginary curve is called an envelope detector. The effect of the time constant RC in envelope detector is that the output follows the input curve and the circuit performs like a demodulator.

Does having a metal plate in shoulder effect the metal detector?

No. The detector head cannot be turned to that amount of sensitivity anyhow and if you could it would drain the batterry very fast. You would also need a larger detector head. Just no.

What is the effect of time constant in envelope detector?

The time constant in an envelope detector affects the speed at which the detector can track changes in the input signal. A longer time constant results in smoother output but slower response to changes, while a shorter time constant provides faster response but may introduce more noise in the output signal. Balancing the time constant is important for optimizing the performance of the envelope detector.
