the period of a discrete time periodic signal cannot be in fractions.
note that the fundamental period of a discrete time signal is given by.

Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
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 discrete and digital signal?
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
Do digital signals control output?
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.
What is digital electronic?
Digital Electronics deals with logic 1 and logic 0, where logic 1 is represented by one voltage and logic is represented by another voltage.(ie. it is a discrete representaiton of analog signals). The main advantage of digital signals over analog signal is that it is less prone to noise.
A discrete variable may assume fractional or decimal values but they must have distance between them?
True
What are the basic signals in signal and system?
analog (continuous) and discrete (discontinuous)
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
Where is the Discrete Fourier Transform used?
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.
What is the difference between discrete fourier transform and fast fourier transform?
discrete fourier transformer uses digital signals whereas the fast fourier transform uses both analog and digital.
What is the difference between a continuous signal and a discrete signal?
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.
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.
What is nyquist Channel capacity formula?
C = 2*B*log2(M) where C --> capacity B --> bandwidth M --> # of discrete signals
Why is it often difficult to divide the adult years into discrete periods?
According to Laura E. Berk, a professor of Psychology at Illinois State University, "the adult years are difficult to divide into discrete periods because the timing of important milestones varies greatly among individuals- more so than in childhood and adolescence." (pg. 431)
What does baud rate measure?
The baud rate measures the number of times the transmission medium can change its state in one second, which is the number of discrete signals in a given second. Baud rate is the speed of transmission when using modems over telephone lines.
Do parenthesis go before or after periods?
Parenthesis go before the period. The period signals the end of the sentence.
What amplifies low frequency signals?
An amplifier! Amplifiers are designed for particular band-widths from fractional-Hz, and even d.c., upwards, but that band can be very wide.
