Expression For Bandwidth Efficiency Of An Encoding Scheme


In this post we'll discuss about Bandwidth and Frequency in details with very practical and accurate examples.


Today we use many television channels but have you ever noticed why some channels are cheap and a few are expensive?

All this is often thanks to their bandwidth being more or less.

The higher the bandwidth of the channel, the upper the speed, which suggests that the info are going to be more capable of processing more.


Bandwidth may be a widely used term in our digital media today.


Bandwidth; there's a complete range of frequencies.


And during this way an individual also listens and speaks at the frequency of Bandwidth.


Today we'll understand this as -

Band + Width ie

Band = strip or bunch of waves, or bundle

Width = width


Now, if we consider the band as waves, any mixed liquids or water, and rounding a pipe to the width, then the broader the pipe, the greater the quantity of water.


The same happens within the exchange of our data.

Now we'll mention Frequency, this word is made from Frequent i.e. fast, fast and eventually suffix cy is added thereto then it becomes frequency i.e. frequency, vibration, or repeatedly.

This frequency features a wavelength.


Frequencies of Bandwidth

Meaning that the frequencies that move downward round the main frequency are the length of their waves.


Like what if we are saying its main frequency

If 300, then 2 more frequencies below it

Which are in 250 and 350 respectively.


Bandwidth's frequencies running around main frequency


Whereas the most frequency is 300. Now the width between 250 and 350 speaks only bandwidth. There are smaller frequencies between them.


Now once we connect it here with Bandwidth, it quickly reaches the bands ie Receiver which is within the bandwidth.

This is the frequency of the Bandwidth that we measure in Hertz.


It is also worth noting here that we measure the digital sort of bandwidth in bps.

While analog forms measure in hertz.


Yes here bps means bits / seconds.

Because where memory is relayed bps like kbps, mbps it's bytes / second.


Like Baseband has digital signal transfer. Therefore, these digital signals also are called baseband signals.

Baseband signals take data within the binary sort of 01 and transfer it to the binary sort of 01 itself.

There is no modulation.


Now briefly or short,

Bandwidth works to deliver data during a fixed amount of your time .

In this way every signal features a bandwidth.


To make this subject more interesting, we'll present our point by example within the combination of both practical and digital.


network transmission during a area


We search data from our mobile phones a day . In some areas it works at a quick speed i.e. if it works at a quick speed, then somewhere it works slow.

This happens because if your service provider keeps you data transmission high speed, then it's to adopt the subsequent method -


Range low + Frequency high

= Data speed high


Range high + Frequency low

= Data speed normal or low


You can see that,

If the service provider Range ie distance or area (low) keeps frequency low, then data speed increases.


On the opposite hand, if the range is raised to high

If it reduces to low, then the info speed becomes normal / low.

The best example of this is often wifi which provides highspeed data within the low range.

All mobile manufacturer companies have already got Bandwidth capability found out for cell phones.

If the bandwidth of the phone increases, then the speed of mobile or television also will increase.


Mobile service providers also keep the info set for a hard and fast limit and a hard and fast time.

If our mobile works on a hard and fast bandwidth, it'll not receive the signal if it gets more or less bandwidth.


At an equivalent time, the bandwidth of television would be very high like 4.2 MHz. So we are ready to enjoy video, audio.


That is, if we would like better communication and video audio from mobile, then its bandwidth should be high.


Since this data is wireless communication, it moves through the electro magnetic (waves) medium, hence its bandwidth is lower.

At an equivalent time, the bandwidth of wired communication is more.


Now we'll take the subsequent practical example to form this subject more interesting.


The primary source of sound is that the air coming into our body.

Vibrations are produced in our vocal cords once we speak, they're very rapid about 100–1000 times per second.

Which is controlled by muscles of the larynx.


A set of waves is produced by the vibration of the vocal cords and therefore the coordination of the Larynx by which we hear that sound. This set speed is that the frequency.


To say that when a sound is produced, it involves two things. the primary is -

Frequency.

Second around this first one ie Main Frequency

Frequencies that move simultaneously.


When the sound is produced, it reaches our ears through air or liquid. These sounds hit small particles present within the air and reach our ears and that we are heard.


It is then converted into these electromagnetic waves then into volts for the aim of remote communication.

These signals are sent only in communication.


The interesting thing is that these signals are formed by Variation of VOLT.

That is, the upper the voltage signal, the upper the facility signal.


Electromagnetic because they need both electric and magnetic properties.


Electromagnetic radiation travels at the speed of sunshine (three million kilometers / second) within the sort of radio waves.


Now we glance at some factors associated with the frequency of our main topic bandwidth.


1 - Frequency of voice of a person is typically 300 to 400 Hz.

2 - While a woman's voice frequency is 500 to 700.

3 - The thinner the sound, the greater the frequency.


4 - Our ears can answer sounds (sound waves) up to twenty - 20,000 Hz.

We cannot hear more or less of this voice.


5 - When the acoustic wave is above 20,000 Hz, it's called ultrasound.

6 - Infrasound is a smaller amount than 20 Hz.

At an equivalent time, there are some creatures which will answer the sound of more or less Hz
