Question

1. You are designing a circuit to add two two-bit binary numbers together, A and B. The result will be stored in the output bits Q1, Q2 and Q3. Write out the truth table for this circuit. The inputs in the truth table must be ordered starting with the lowest binary number in the first row and the highest binary number in the final row. Make sure the MSB is on the left, and the LSB is on the right when you write your binary numbers. 2. An inverting amplifier circuit has a feedback resistor of value 10k Ohms and an input resistance of 1k Ohms, and an open loop gain of 5x10$^3$ at 50 Hz. Calculate the closed loop gain of the circuit, showing the equation you use to calculate the result. Why are Op-Amps generally not used in their open-loop configuration (do not write more than 20 words)? 3. You are designing an analog to digital converter (D2A) using an R2R ladder and a comparator. You will be measuring the voltage range between -5V and +5V, you want to have a resolution of 1x10$^{-3}$ V. How many IO lines would you need to connect your D2A convert to a computer? Give one reason why you would use a flash converter over a converter with an R2R ladder.

You are designing an analog to digital converter (D2A) using an R2R ladder and
a comparator. You will be measuring the voltage range between -5V and +5V,
you want to have a resolution of 1x10^-3 V. How many IO lines would you need to
connect your D2A convert to a computer? Give one reason why you would use a
flash converter over a converter with an R2R ladder.
