1. What are the advantages of using digital signal processing compared to analog processing? (Select all that apply.) a. Enhancement of information b. Upgrading performance by changing software c. Ability to work directly at radio carrier frequency in digital domain d. ability to store information signal 2. Strange requirement of real-time signal processing is a. to process signal always in milliseconds scale b. to process signal always in microseconds scale c. to process algorithm before next signal sample arrives d. to process signal with real data instead complex presentation 3. Following statement is in contrast with respect to DSP processor. a. DSP processor is built on Harward architecture b. DSP processor has only one address bus and one data bus c. DSP processor has multiple data bus and address buses d. DSP processor is built with hardware multipliers and accumulators 4. Unit impulse function 8[n]: = when n = 0. a. 1 b. C. -00 d. 0 5. Continuous time signal sin (2nt) is sampled at a rate of samples per second. The resultant output sequence would look a like a. triangular wave b. square wave c. impulse train d. flatline 6. Continuous time signal sin (37t) is sampled at a rate of 4 samples per second. At what sample output value reach to peak value (+1V)? Hint. Simulate with sample index n = 0 to 20 samples. a. n = 0 b. n = 6 c. n = 12 d. n = 4 7. In Up-sampling, a. the information content of the signal is doubled b. the information content of signal remain same c. the information content of the signal decreases d. information content depends on ADC number of output bits
