Challenge Problems
Push your limits with challenges.
Question 1
Consider a BCD D/A converter with a step size of 5mV and an expected output for the input '74'. Determine the analogue output as well as the impact of a ±0.1% error.
💡 Hint: Multiply the step size with the input value and then apply the error percentage.
Question 2
Given a BCD D/A converter allowing inputs 00 to 99, if the maximum weight of LSD was 8, calculate the corresponding output if the BCD input is 56.
💡 Hint: Use the position of each bit to calculate combined weight outputs.
