Analog signals are continuous while digital signals are discrete
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.
THE TERM CONTINUOUS SIGNAL AND DISCRETE SIGNAL CLASSIFY THE SIGNALS ALONG THE TIME (i.e. horizontal axis) where as THE TERM ANALOG AND DIGITAL SIGNAL CLASSIFY THE SIGNAL ALONG THE AMPLITUDE (i.e vertical axis) we often confuse our-self with continuous time and analog signals. An analog signal is a signal which can take any amplitude in continuous range that is signal amplitude can take infinite values on the other hand a digital signal is one whose amplitude can take only finite numbers of values
No, some electronic devices use analog signals as their input/output others may use digital signals as their input/output; some equipment uses an analog signal as the input and outputs a digital signal. Be sure to use the correct signal and signal strength otherwise you may damage your electronic device.
While processing a signal through a channel, it is preferred to sample it. It is because of the following reasonsAs we send only the samples, the gap between samples can be used to send another signal.Multiplexing is possibleSamples occupy less space than signalsTotal signal may not be required to recover dataAnd hence we use samples which are nothing but discrete time signals. hence, it is called discrete time signal processing.
True
analog (continuous) and discrete (discontinuous)
Analog signals are continuous while digital signals are discrete
The Discrete Fourier Transform is used with digitized signals. This would be used if one was an engineer as they would use this to calculate measurements required.
Analog refers to waves continuously varying in strength and quality, while digital refers to communications signals or information in a binary form - with values represented as discrete symbols. Analog signals are continuous and can have an infinite number of values, while digital signals use discrete 0 and 1 values.
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
Two forms of electrical signals are analog signals, which vary continuously over time, and digital signals, which represent data as discrete values. Analog signals can take on any value within a range, while digital signals have specific voltage levels to represent binary data.
The two basic kinds of electronic signals are analog signals and digital signals. Analog signals are continuous and can take on any value within a given range, while digital signals are discrete and represent information as a series of binary values (0s and 1s).
The Laplace transform is used for analyzing continuous-time signals and systems, while the Z-transform is used for discrete-time signals and systems. The Laplace transform utilizes the complex s-plane, whereas the Z-transform operates in the complex z-plane. Essentially, the Laplace transform is suited for continuous signals and systems, while the Z-transform is more appropriate for discrete signals and systems.
A continuous signal is one that is measured over a time axis and has a value defined at every instance. The real world is continuous (ie. analog). A discrete signal is one that is defined at integers, and thus is undefined in between samples (digital is an example of a discrete signal, but discrete does not have to imply digital). Instead of a time axis, a discrete signal is gathered over a sampling axis. Discrete signals are usually denoted by x[k] or x[n], a continuous signal is x(t) for example. Laplace transforms are used for continuous analysis, Z-transforms are used for discrete analysis. Fourier transforms can be used for either.
