We need an ADC that can accept input voltages ranging from 0 to 5 V and have a resolution of 0.02 V. How many bits must the codewords have?

Given x(n) = {0,4,2,3,0,3,2,4} array, find FFT and obtain number of operation.

An analog signal having frequency as 7,30 KHz is digitized and stored in a file. If the total time of the signal is 15 min and the file size is 2,45 Mbit , which answer is correct? O a. Bit = 8 bits Data Rate = 116,8 Kbps O b. Bit = 7 bits Data Rate = 70,1 Kbps O c. Bit = 4 bits Data Rate = 58,4 Kbps O d. Bit = 4 bits Data Rate = 77,9 Kbps O e. Bit = 8 bits Data Rate = 58,4 Kbps

3. Some GPS receivers use 1 bit ADCS (Analog-to-digital Converters) to sample and quantize the signal i.e. the output of the ADC is simply 2 quantization levels: -1 or +1. This is typically done to save on power. (a) What is the quantization SNR? How does it compare to typical thermal noise SNR of a GPS signal before correlating with the CDMA code? (b) Justify, how come it is possible to sample the signal using a single bit and still get good performance.
