Question 76

A microcontroller processes an input sensor reading, stored in the variable signal.

The two algorithms below have the exact same computational purpose.

Algorithm A

accum ← signal LEFTSHIFT 3
output ← accum - signal

Algorithm B

output ← 0
FOR step ← 1 TO 7
    output ← output + signal
ENDFOR

State this common computational purpose.
