A pulse or pulses are analog signals, however, if you define anyting below low level threshold as logic 0 and above high level threshold as logic 1, the same pulse can be treated as 0-1 logic signal so you can call it digital signal
If you are interested in the actual value or magnitude of the signal for example the actual voltage level of the signal then you should consider it as a analog signal.
But if you are only interested in a high or low value of the signal like in binary i.e above a certain magnitude the signal is high (1) and below that it is low (0) then the pulse should be considered as a digital signal.
It can be considered digital if it meets logical threshold levels, but basicaly it is an analog signal with a start voltage, a final voltage and dv/dt raising an falling edges.
well !!!! i personally think is that if we take a very high frequency analog signal whose freq tends to infinity then we would get the square pulse. we get the digital signal because of analog.it is just the representation of analog signal between two voltage values.
An digital signal is simply ones and zeros. It is normally obtained via a decision device imposed on an analog signal.
Of course, the more widely used definition is the one based on gut instinct. Anything that "looks digital" is digital.
i think digital signals are discrete time discret amplitude signals,they just pulses at instances of time.but if u stretch the pulse u get a analog continuous signal.
square pulse is a analog signal.
Thats True, If u stretch your digital signal, it looks like a analogue signal i.e at higher frequency. Because all the signal have some slew rate.
But as long as the slew rate of the ur signal is very small,then it is digital.
So this depends on where your trying to input your square wave signal & what is the operating frequency?
