Prоblem Stаtement The fоllоwing progrаm prompts the user to enter the size of the fertilizer bаg, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the price of the fertilizer per pound and the cost of fertilizing per square foot. However, the program contains one or more logic errors. Select the logic error(s) present in this code, from the list below. 1. #include 2. #include 3. 4. using namespace std;5. 6. int main()7. { 8. double cost;9. double area;10. double bagSize;11. 12. cout
1. Is the 18-bit, 250MS/s ADC thаt yоu did the cаlculаtiоns fоr in problems 3 through 6 feasible/realistic? Yes No 2. What are the most significant concerns/challenges with the feasibility of the design of this ADC amplifier dc gain amplifier bandwidth clock jitter capacitor size/area both b) and c) 3. What could you do for the ADC design from problems 3 through 6 to allow the first stage amplifier settling requirement to be realized? increase the amplifier power to 10 watts increase the resolution and gain in the first stage interleave multiple ADCs increase the sampling capacitor sizes 4. What is the physical source of kT/C noise? switch resistance sampling capacitance switch capacitance both a and b 5. You measure a peak signal to noise plus distortion ratio of 86dB for your converter. How many effective bits of resolution does it have? 11 bits 12 bits 13 bits 14 bits 6. An new 6G basestation receiver requires an ADC that can digitize a bandwidth of 50GHz with 8-bit resolution. The best ADC architecture for this application would probably be: A pipelined ADC. A folding ADC. A flash ADC. A time-interleaved ADC 7. The clock jitter based SNR for an ADC is primarily limited by? Sample rate Sampling switch size Input frequency ADC resolution 8. The main factor that limits the implementation of high-resolution FLASH ADC is which of the following: the size of the required inductors the number and required accuracy of the comparators the input capacitance b) and c) 9. For a Nyquist-rate ADC, oversampling provides an additional dB of signal-to-noise ratio for each doubling of the oversampling ratio. 3 6 9 15 10. Compared to a 1 bit per stage design, a 1.5-bit per stage RSD pipelined A/D converter is much less sensitive to comparator offsets l/f noise opamp offsets both a) and c) 11. The challenge(s) that are specific to time-interleaved data converters is (are) Jitter clock skew Excessive speed oversampling 12. A missing code is indicated by a DNL for that code of 0 -1 +1 less than -2 13. A filter is typically required before an ADC to prevent oversampling aliasing offset l/f noise 14. If a 15.5MHz input signal is sampled by an ADC that is sampling at 25MHz, at which frequency does the resulting signal end up? 7MHz 3MHz 5MHz 8MHz 15. In an ADC for which the SNDR is limited by harmonic distortion, the harmonic distortion is primarily caused by: Resolution (i.e. number of bits) INL DNL capacitor size
