Digital Electronics - Engineering

Q1:

Mark the false statement:

A since wave-shape of a digital signal is unimportant, linear amplifiers are not required

B the precise amplitude of a digital signal is also unimportant provided two voltage levels (0 and 1) are quite different

C the leading and trailing edges of a digital signal need not be sharp

D actual digital waves have rise and fall times of the order of a few nano seconds

ANS:C - the leading and trailing edges of a digital signal need not be sharp
