Question

What do you understand by analogue and digital quantities

Answer 1

ANALOG AND DIGITAL QUANTITIES— Ananalog signal is sampled or tested repeatedly over aperiod of time to determine the characteristic thatcontains  the  analog  quantity.  The  sampled  analog  valueis converted to the nearest binary value or quantity. Thebinary value is then encoded into a code acceptable tothe digital equipments that use the data. Standardizedbinary   words   called   BAMs   (binary   angularmeasurement) are used to transmit angular, range, andheight values between digital equipments in shipboardcombat direction systems. Other coding systems suchas Gray code or binary-coded decimal (BCD) are alsoused to transmit converted values
