Design and simulate a summing amplifier with the ability to sum different number of small-sized coin (S), middle-sized coin (M) and large-sized coins (L) and produce the result in total points available. S has 1 point, M has 2 points and L has 3 points. The values 7, 5 and 9 are used as input. All calculations must be shown and Multisim circuit output is required.
May I know where do I start? Here is my attempt. (Forum.ms14)
