Final answer:
Option B is answer. The symbol rate for a bipolar NRZ data sequence at 1 Mbps bit rate is also 1 Msym/s since each symbol represents one bit.
Step-by-step explanation:
The question from a student is regarding symbol rate and bandwidth in a digital communication system with a bipolar NRZ (Non-Return to Zero) data sequence at a bit rate of 1 Mbps and a carrier frequency at 100 MHz. The symbol rate in such a sequence is the same as the bit rate because, for bipolar NRZ, each symbol represents one bit. Thus, the symbol rate is 1 Msym/s (megabaud). The bandwidth of a signal can vary based on several factors, including the modulation technique used and the presence of filtering. However, a rough estimate for the minimum required bandwidth in a binary signaling system like bipolar NRZ is equal to the bit rate, so the bandwidth would be 1 MHz. Therefore, the closest answer given the provided choices would be:
Symbol rate: 1 Msym/s, Bandwidth: 1 MHz
This is not listed among the provided options, which suggests either an error in the options or additional context may be needed to choose the best match from them. If we consider typical values, the most accurate choice among the given options would be b. Symbol rate: 1 Msym/s, Bandwidth: 50 MHz, representing a compromise for practical systems that may include additional spectral spread due to filtering.
