The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.

When analog voice signal converts into digital signal the bandwidth needs 64kbps. Why?
PCM technique is used to convert analog voice signals into digital. In PCM the analog frequency is first sampled and then converted into binary bits. Each samples are taken as 8bits long. Basic communication theory requires that a minimum sampling rate of twice the frequency of the signal to be sampled will result in an accurate representation of the original signal.Human voice can have max 4000hz frequency, therefore sampling rate should be 8000 samples/sec.Which implies required bit rate for transmitting voice is 8000*8 = 64000 bits/sec = 64kbps.
What is the relation between the bandwidth of a signal before and after it has been encoded using spread spectrum?
there is no basic difference btw the BW. it is the same before & after the SS encoding
What is an analog sensor?
An analog sensor is a device that measures an analog quality (such as temperature, wind speed, sound frequency or velocity). Many of us fail to recognize the difference between qualitative and quantitative measurements. Quantitative descriptors are actually just the result of counting something; seventeen marbles, five folding chairs, three apples... Qualitative descriptors are the result of estimating something; eight cups of sliced apples, a five pound bag of marbles, the current room temperature. When we use a scale to measure something, it's called "qualitative"... or analog. Converters are available that allow a computer to achieve a close approximation of an analog measurement, but for the computer to use the value it must first be converted to a digital signal. Inside the computer, that digital signal is all ones and zeroes, but many of them can be put together to represent a very large number. If that doesn't help, perhaps a basic physics class or even a computer "digital logic" class might be beneficial.
What is the basic function of an amplifier?
An amplifier will amplify a signal. For example, the antenna in a radio will receive an extremely weak signal; before it can be converted to a sound, it must be amplified (made stronger), by a factor of several million. Of course, since you can't produce energy out of nothing, an amplifier doesn't actually produce the energy for the strong version of the signal - it requires a power supply.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
What are the elements of electronic data processing?
An answer is still required...There are four basic elements of an Electronic Data Processing (EDP) system. These are:1. Hardware2. Software3. Procedure4. Personnel
What are the basic elements of communication system?
The basic elements of a communication system are:A senderA mediumA receiver
What is the basic principle of digital television?
Digital television is simply the process of broadcasting a digital signal, instead of an analog one. This results in better sound and picture quality, as well as increased coverage.
Where can one find the definition of digital computer?
The definition of digital computer can be found listed on nearly any dictionary website such as TheFreeDictionary. The definition is really rather basic in that a digital computer is simply a device for processing information.
What are the capabilities of digital communication systems?
A digital communication system consists of six basic blocks. The functional blocks at the transmitter are responsible for processing the input message, encoding, modulating, and transmitting over the communication channel.
My question is, what is digital TV?
Digital television has nothing to do with cable or satellite. The only thing digital television means is that the signal that is distributed is a digital one and not analog. The big switch that occurred two years ago means that everyone receives a digital signal. Now, if you want content, you are going to have to subscribe to a cable or satellite provider. What you probably saw was a basic service that gave you local channels, but not much else.
