MATLAB (Matrix Laboratory)

i asked you a question u could not provide me with an answer. and now you are re- asking me my question. does question answers question?

Here

In a MOSFET, the gate current is essentially zero because the gate is insulated from the channel by a thin layer of oxide, typically silicon dioxide. This insulation prevents any DC current from flowing into or out of the gate, allowing the gate to control the channel without dissipating power. The gate voltage influences the channel conductivity through an electric field rather than through current flow, which is a key feature of MOSFET operation. Thus, the gate primarily serves as a capacitively coupled control terminal.

MatLab means MATrix LABoratory. It converts the signals into matrices and performs various operations on them. Hence, it is used mainly in applications where there is a need to convert data from one form to the other.

When NPN transistors are used in the most common amplifier configurations, they require a power supply with positive polarity with respect to common terminal. PNP transistors instead require a negative power supply. Over many years the positive power supply has become a design standard. This means that, for "Common Emitter" and "Common Collector" amplifiers, NPN transistors must be used. The same was once true for logic circuits: for positive power supplies, the logic gates would be built from N-channel FETs. But since the 1980s an improved setup has been used: CMOS logic which is built from approximately equal numbers of P-channel and N-channel transistors.

npn is mostly used because in npn electron current is greater the hole current.whereas in pnp hole current is greater than electron current. it is a people choise and basicaly and a manufacture choice. nobody wants to be negative. logic chips were developed for positive potential that doesn't mean that these chips cannot be used at a negative potential quite the contrary as long as the chip sees a positive voltage across them they work. you may develop a computer whereb\y the logic is gnd as positive and -5v as -vss. so you see it is a human choice.

A virtual image is a copy of an object formed at the location from which the light rays appear to come. Whereas a real image is a copy of an object formed at the point where the light rays actually meet.

Preprocessing images commonly involves removing low-frequency background noise, normalizing the intensity of the individual particles images, removing reflections, and masking portions of images.Image preprocessing is the technique of enhancing data images prior to computational processing.

A filter is an effect that can be added to an image that affects the overall appearance, or apearance of a selected area, of an image.

Impossible to give a specific answer without more information. Is it a BJT or a FET?

Most general answer is you first have to understand the circuit using the transistor and what it's supposed to do. Then,

1. Check that the power supply voltages are correct.

2. Check that the DC biases are correct.

3. Check that the input signal is correct.

4. Check the output.

But you have to know in advance what to expect.

why does have to short-circuit secondary wire of current transformer ?

The full wave rectifier is a means of converting alternating current (ac) into direct current (dc). It is done with either the use of 2 diodes coming off a center tapped transformer, or by using a bridge rectifier, which conists of 4 diodes ganged together in a certain configuration. As it's name implies, it converts both the positive going and the negative going parts of the sign wave into useable dc, and therefore is more efficient than a half wave rectifier, which only converts 1/2 of the complete sign wave into useable dc.

please tell me ... which recent topics are going in digital image processing for research area .

If the orientation of the letter "e" on the slide is exactly the same as it appears in this response, then the image of the "e" would be an inverted reflection.

In lamens terms, the "e" would be upside down inside the microscope.

When you convert digital signal to analog, it is called as an analog signal.

The device used is called digital to analog converter.

The fundamental components of digital image processing are computer-based algorithms. Digital image processing allows a much wider range of algorithms to be applied to the input data and can avoid problems such as the build-up of noise and signal distortion during processing.

Image processing is the method of processing data in the form of an image. Image processing is not just the processing of image but also the processing of any data as an image. It provides security.
