Electronics Engineering

The purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose.

Impedance matching us used to make the circuits compatible based on electrical characteristics of a particular circuit from one section (or stage) to the next.

It work like a master slave flip flop if its not a logic 1 then its a 0.

It is a kind of transformer used to make changes in accordance with the voltage connected to substituting current hardware. It associations are utilized as a part of a few places, for example, uninterruptible power supply units for PCs, and in the tanning bed industry....

OR gate is an electronic circuit that takes 2 or more input signal bt produces one 1 output signal. the output is true(ie: 1) if any of the 2 input is true, else the output is false(ie: 0).

eg:-

A B A+B

0 0 0

0 1 1

1 0 1

1 1 1

here '+' sign indicates the OR gate.

You can calculate h parameters in CE and CB configurations by the diagram that you are looking at, but if need be there are a few formulas you can use.

A CMOS buffer is two stage inverter, or two inverters connected together in such a way that the output of first goes directly into second one.

what are the limitations of forier series over fourier transform

c=q/v c=q/v

They are the same thing; vibrations of the electromagnetic field. Microwaves have a frequency between 0.3 GHz to 300 GHz, and radio waves have a frequency between 3 Hz to 300 GHz. So microwaves are a type of radio wave.

Human beings do exhibit an alternation of generations, but the haploid phase is extremely deemphasized while the diploid phase is overwhelmingly dominant. The haploid phase in humans that results from meiosis is restricted to only one cell, either an egg in the female or a sperm in the male. There is never a multicellular haploid structure as there usually are in plants. If such a multicellular haploid structure is required for a true alternation of generations, then humans do not exhibit alternation of generations. The human organism grows by mitosis (the diploid phase) only after fertilization. A plant sporophyte is diploid and it produces spores by meiosis. Humans, like plant sporophytes, are diploid and make haploid gametes by meiosis.

Your total milliamp range is 4 to 20 milliamps. 4 Ma being 0mmH2o and 20 Ma being 2500mmH2o. So 1250mmH2o is 50% which is equivalent to 12Ma signal.

Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.

Triangular wave generator is a device (for eg NE555 timer) that generates a triangular wave by integrating a square wave. In applications an ICL8038 IC can be used to generate all types of waves.

The input voltage range for the Toshiba power supply is AC 100V - 240V. The output voltage is DC 19V / output current is 4.74A. This power supply comes with a power cord and packaging will state voltage recommended for the product.

An oscillator has a tuned circuit (inductance+capacitance) to determine the frequency. When the inductor is tapped to give the required phase-shift for oscillation it is a Hartley oscillator. When the capacitance is tapped it is a Colpitts.

Phase shift does occur, but the parasitic capacitance of a diode is so tiny compared to the external circuit resistance that it is virtually impossible to observe.

No. For electrons to flow, you need a current.

Almost anything. One definition of robot is "artificial agent" (a better definition is in the link below). Artificial just means someone made it, agent means it does something for someone (my favorite robot is the dishwasher - someone built it to wash dishes for me). Many people assume "agency" includes the ability to act by itself (autonomy), or at least look like it can. These days most of the really popular robots are exploring places people can't go yet (Voyager left the solar system not too long ago, Spirit and Opportunity are still running around Mars) and doing things too dangerous for humans to do safely (like hunting for roadside bombs in war zones or searching the bottom of the ocean). I used to work with a parts placer in an electronics assembly plant, it took very small parts from reels and bins and placed them on circuit boards. Some car manufacturers use big industrial robots for welding and lifting cars and trucks. Nanotechnology is finally catching on, with motors and wheels the size of atoms. I have seen pictures of remote control robots for doing surgery from somewhere outside the hospital, like from another country. Then there are the vacuuming robots. Anything you can build to do something for you is basically a robot. Oh yeah, don't forget battlebots! Some of us like the sound of smashing and tearing metal.

Not clear what your question is. First of all, circuits are not classified as DC and AC. Circuits are what they are, and you can apply either AC or DC to any circuit. However, considering a circuit that was designed only for use with DC applied. Still your question is unclear. What is transformer action? "Transformer Action" happens in a transformer.

This question does not make any sense. "Real world" load, from the perspective of the power producing generator, can be reduced to a lumped resistance in series with a reactive component (either inductive or capacitive). In reality, the load connected to that generator has series elements and parallel elements.

Digital signal processing is used instead of complicated analogue circuits.

It is used in mobile phones and PA amplifiers to prevent feed back (howl round).

A microphone placed near a speaker, will cause the microphone to hear itself and cause an annoying howl. By applying some of the mic signal in antiphase to the local speaker, this can be stopped. This allows simultaneous conversation using hands free, which would be impossible without digital signal processing.

It can also be used to clean up old recordings to remove noise.

All sorts of effects can be applied to an audio signal, such as reverberation, echo and tone.

Once the signal is in digital form, all the processing can be done by a program using mathematical processes and applied digitally to the original signal. Changes can be made by simply altering a few lines of code.

before digital processes, sound had to be altered by complicated, expensive, circuits that could not be changed easily.
