Electronics Engineering

Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

What does Thevenin's equivalent circuit consists?

The Thevenin's equivalent circuit consist of a voltage source in series with a resistor.

How much k ohms are in 680.000 ohms?

One kilohm = 1,000 ohms, so without even thinking about the decimal point:

First, .960 is nearly one (1.000), so .960 kohm is almost a full kilohm, or nearly a thousand ohms.

So, since the answer will include the digits 9, 6, and maybe some zeros following, what are the possibilities: 9.6, or 96, or 960 or 9600 ohms? The logical choice is 960 ohms

What is meant by 0 volt?

Means that there are Zero Volts or said another way, a zero potential.

What difference between amplitude modulation and double sideband suppressed carrier?

Both are forms of AM but in suppressed carrier a filter is used to attenuate the carrier frequency prior to transmission. This is usually done to reduce the total transmitter power consumption. An ordinary AM radio cannot correctly receive suppressed carrier stations, you must have a receiver that replaces the carrier prior to the detector stage.

What are DC Choppers?

Dc chopper is a static device which converts constant dc source to variable dc.

How many bits does a 1 frame per second have?

In order to know how many bits/second there are in 1 frame/second, you need to know how many bits are in that frame. In a typical asychronous serial protocol with 8 bits per frame, the bit rate would be 0.125 bits/second. If you are talking the IP network layer of TCP/IP, then the frame size is very dependent on the underlying message payload and headers.

The original question, by the way, is invalid. Its asks "how many bits does...", but it should have asked "how manys bits per second does...".

What determines the actual magnitude and direction of current through voltage source?

The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).

Four 50 ohms are connected in series calculate the current in the circuit?

The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.

The series resistance is 4 x 50 = 200 Ohms. You would need additional information to get the current; usually this is calculated from the voltage. current = voltage / resistance.

In a circuit is it possible that the sum of the voltage dissipated across each resistor larger than the voltage provided by the source How about the power?

No. This would mean more power is used than is provided - an impossibility. It is possible that you may not be accounting for a power source in your circuit, or have the actual source modelled incorrecty.

What is the significance of status signals?

Status signals are indicators of an individual's social standing or prestige within a group or society. They can manifest through various forms, such as material possessions, behaviors, or affiliations, and play a crucial role in social interactions and hierarchies. By displaying status signals, individuals can influence perceptions, gain respect, and assert dominance or belonging. Additionally, these signals often shape social dynamics, fostering competition or collaboration within communities.

What is meant by pinch off voltage in fet?

Pinch-off voltage in a Field Effect Transistor (FET) refers to the specific gate-to-source voltage at which the channel conducting current begins to 'pinch off' or constrict. Beyond this voltage, increasing the gate voltage does not significantly increase the drain current; instead, the current becomes relatively constant as the channel narrows and limits the flow of charge carriers. This phenomenon is crucial for the operation of FETs in saturation mode, where the device is used for amplification and switching applications.

What is the formula for voltage?

Voltage is the current times the resistance or

V = I R

Voltage= Current × Resistance

**This is the equation for "Ohm's Law". It assumes that you are evaluating an Ohmic device or circuit.

Why can't you broadcast in 1080p?

Some years ago, broadcasters began upgrading studios to HD. A studio has a typical life of 10 years, depending on the use. Over the space of a ten year period, the majority of broadcast studios will be capable of producing content in HD. As the process started, 1080i was the highest resolution and frame rate to be considered. Even now, there is very little equipment capable of handling 1080p in a live production chain. Having 1080p cameras is of no benefit to broadcasters if the vision mixer or switcher cannot use the format. Additionally, recorders, image processors, switches, cables and all other parts of the infrastructure need to be 1080p capable. The full bandwidth of 1080i is about 1.5Gb (1500 megabits per second). 1080p requires 3Gb, twice the data rate, therefore twice the storage space and twice the bandwidth for broadcast to viewers. Most broadcast manufacturers have 1080p equipment on their roadmap for the future but it will be a number of years before it will be realistic to equip broadcast facilities for 1080p. Broadcasts to homes are heavily compressed, allowing an HD channel to use as little as 5Mb of bandwidth. To use 1080p, the data rate will typically have to approach 10Mb if the improvement in quality is to be seen by the viewer. We will have to wait until production studios are equipped for 1080p, broadcasters can store 1080p and service delivery platforms (cable and satellite) can handle the additional data rate without decreasing he number of channels being delivered. None of these are likely to happen until companies can see an increase in revenue for delivering 1080p content. Indeed, many are still not committing to HD 1080i production for similar reasons - the cost of doing so is not being recouped by additional revenues. For the time being, we will have to be content with 1080p programs being available from local sources such as Bluray. Broadcast 1080p will remain no more than an ambition for a few years yet.

Tell you what an intermediate frequency amplifier do?

The intermediate frequency (IF) amplifier lies between the mixer and the demodulator. The mixer shifts the input radio frequency (RF) signal into the range of the IF amplifier. The IF amplifer is a band pass amplifier, so only RF signals that are the IF frequency distance away from the local oscillator in the mixer can pass through to the demodulator. This process is called the superhetrodyne process.

Why downlink is greter than uplink?

The downlink is greater than the uplink on most internet connects due to overall demand for bandwidth. Downloading takes up a majority of internet usage and connections are optimized for it.

What does LM in LM380 stand for?
