The Total solution for NCERT class 6-12
Digital signals
(i) Donot provide a continuous set of values,
(ii)Represent values as discrete steps,
(iii) Canutilize binary system, and
(iv) Canutilize decimal as well as binary systems.
Which ofthe above statements are true?
(a) (i)and (ii) only
(b) (ii)and (iii) only
(c) (i),(ii) and (iii) but not (iv)
(d) Allof (i), (ii), (iii) and (iv).
(c)Answer:
A digital signal uses┬аthebinary (0 and 1) system for transferring message signals. Such a system cannotutilise the decimal system (which corresponds to analogue signals). Digitalsignals represent discontinuous values.
