All Q

Given is a channel with a capacity of 20Mbps and a bandwidth of 3Mhz. What signal to noise ratio is required to achieve this capacity? A digital signaling system is required to operate at 9600 bps. i. If a signal element encodes a 4-bit word, what is the minimum required bandwidth of the channel? ii. Repeat part (a) for the case of 8 bit words. Using Nyquist's equation: C=2B log2M We have C = 9600 bps i. log2M=4, because a signal element encodes a 4-bit word Therefore, C=9600 = 2B * 4, and B= 1200 Hz ii. 9600= 2B * 8, and B = 600 Hz A digital system is required to operate at 19,200 bps. a) How many signaling levels are required if the channel bandwidth is 1920 Hz? b) If a signal element encodes a 6-bit word, what is the minimum required bandwidth of the channel
