Why FDM is for analog signals and TDM is for digital signals?
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
Difference between digital signal and analog signal?
Analog signals are continuous where digital signals are discrete. Anolog signals are continuously varying where digital signals are based on 0's and 1's (or as often said------- on's and off's). As an analogy, consider a light switch that is either on or off (digital) and a dimmer switch (analog) that allows you to vary the light in different degrees of brightness. As another analogy, consider a clock in which the second hand smoothly circles the clock face (analog) versus another clock in which the second hand jumps as each second passes (digital). Digital computers work with a series of 0's and 1's to represent letters, symbols, and numbers. In addition, numbers are represented by using the binary code (where only 0's and 1's are used). Number Binary equivalent 1----------------------------------------------1 2---------------------------------------------10 3---------------------------------------------11 4--------------------------------------------100 5--------------------------------------------101 6--------------------------------------------110 7--------------------------------------------111 8-------------------------------------------1000 and so on. So each number (that we are accustomed to, such as 5) is represented by 0's and 1's. Morse code uses dits (or dots) and dashes. Digital signals are similar to Morse code. The signal is either a dit or a dash for Morse code and it is either a 0 or 1 for digital. A series of these dits and dashes might represent SOS to a navy radio man, and a series of 0's and 1's might represent the question mark to a computer.
What are Reflected codes?
a modified binary code in which sequential binary numbers are represented by expressions that differ only in one bit, to minimize errors.
What is difference between analog and digital communication system?
Analog systems are what we can call wave systems. they have a value that changes steadily over time and can have one of an infinite set of values in a range. The term digital refers to the fact that the signal is limited to only a few possible values. in general, digit signals are represented by only voltages on a wire -0 volts ( which we called " binary o " or just "o" ) and 5 volts ( which we call " binary 1 " or just"1" ).
Analog signal vs digital signal?
A: Analogue is a signal DC with varying amplitudes. Digital is a state defined as true or false or machine language '1' '0' Digital must change states to supply information while analogue it has only to change amplitude
What is the basic difference between analog and digital system?
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
Why do people only consider voltage signals in communication electronics?
Voltage Signal Is considered Because Voltage Signal's this case digital signal] is the carrier of the data [in binary form]
What is the purpose of a digital converter?
A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.
Why is binary number system used in digital electronics?
Binary is simpler than decimal. And it is easy to represent binary numbers with signals, since only two states are required. For example, a low voltage state might represent a zero, and a high voltage state might represent a one. Or vice versa.

Difference between binary data and digital data?
only difference is that binary is only consists of 0 and 1 bits,where as digital means it may either contain binary bits (0,1), or contain the numeric digit (0-9), mainely digital means just the number between 0 to 9
What is the purpose of a digitizer?
A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.
What advantage do digital television signals provide over analog signals?
Digital signals produce a higher quality picture and many programs can be broadcast on a single digital channel, whereas only one program can be broadcast on an analog channel
What is the base 2 system?
It is often called Binary. There are only 2 symbols, usually "0" and "1". Digital devices often use Binary.

Is a 3d bar code digital or anolouge?
A 3D barcode, also known as a 2D barcode, is a digital barcode. It consists of squares, dots, or other patterns arranged in a two-dimensional matrix. Each square or dot represents binary code that can be scanned and decoded using a barcode reader or smartphone app.
What is binary cyclic code?
The reflected binary code, also known as Gray codeafter Frank Gray, is a binary numeral system where two successive values differ in only one bit.Here is an example of a 4-bit Gray code:0000000100110010011001110101010011001101111111101010101110011000
