Digital signals (i) Do not provide a continuous set of values (ii) Represent value as discrete steps (iii) Can utilize binary system (iv) Can utilize decimal as well as binary systems State which statement(s) are true? (a) (1), (2) and (3) (b) (1) and (2) only (c) All statements are true (d) (2) and (3) only
Correct option is C) A digital signal uses the binary (0 and 1) system for transferring message signals. Such a system cannot utilize the decimal signals, represent discontinuous values line-of-sight communication, which is nothing but space system (which corresponds to analogue signals). Digital signals represent discontinuous values.
