Decoder Design

Click For Summary

A 3:8 decoder can be designed using a 5:32 decoder by grounding inputs X3 and X4, effectively limiting the inputs to three. Conversely, a 5:32 decoder can be constructed using multiple 3:8 decoders to handle the additional inputs. The discussion raises a question about whether the answers for parts a and b are swapped, indicating potential confusion in the design process. Participants are encouraged to verify the solutions provided. The focus remains on the correct implementation of decoder designs in digital logic.

Homework Statement

a) Design a 3:8 Decoder using 5:32 Decoder.
b) Design a 5:32 Decoder using 3:8 Decoder.

Homework Equations

The Attempt at a Solution

( X₃ and X₄ are grounded , because we need 3 inputs only )
Could someone check my answer please ?

Are your a and b answers swapped?

Thread 'Rectifier Meter'

I am confused with the question it falls under the topic of Rectifier meter, I feel the peak of the sine input need to be provided to calculate the full scale reading of the meter, 1mA is the resolution of the meter. Any hint to solve this problem?
