QUESTION 9 Determine the "M" value and number of data bits that can be represented by a single symbol using FSK where the possible frequency values per symbol can be {100 Hz, 200Hz, 300Hz, 400Hz, 500Hz, 600Hz, 700Hz, 800Hz}. a. M=2, N=1 bit per symbol b. M=4, N=2 bit per symbol o C. M=6, N=3 bit per symbol d. M=8, N=3 bit per symbol QUESTION 11 A single symbol represents the following logical values: 00, 01, 10, 11. At a baud rate of 2400, what is the resulting bit rate using Hartley's Law? a. 1200 bps b. 2400 bps c. 4800 bps d. 9600 bps . QUESTION 22 You digitize an analog signal that has a frequency bandwidth of 4kHz, using a bit depth of 8. What data rate must be supported? a. 640 kbps b. 64 kbps c. 32 kbps d. 256 kbps QUESTION 20 An analog signal with a bandwidth of 36MHz is sampled at a frequency (fs) of 36,000,000 samples per second during the ADC (analog-to-digital conversion) process. What is the outcome of the received signal after the DAC (digital-to-analog conversion) process? a. the signal will have experienced aliasing ob. the signal will not experience aliasing c. the signal will perfectly represent the original pre-ADC analog signal O d. none of the above describes the outcome QUESTION 6 According to Hartley's Law, which statement below is true? a. if a symbol represents two logical bits, then M equals 4 values per symbol b. a symbol represents a logical bit, therefore M always equals 2 C. M represents the number of logical bits represented by a symbol d. the number of symbols and logical bits are always equal
