1. Binary symbols are used.
   Answer:
   When two symbols are used, the bit rate and baud rate are the same. That is because:
   2 = 2¹, so n = 1 bit/symbol
   bit rate = baud rate x n = 100 symbols/sec x 1 bit/symbol = 100 bits/sec = 100 bps

2. Multivalued symbols (16 symbols) are used.
   Answer:
   When more than two symbols are used, the bit rate and baud rate are the different. For 16 symbols:
   2 = 2⁴, so n = 4 bits/symbol
   bit rate = baud rate x n = 100 symbols/sec x 4 bits/symbol = 400 bits/sec = 400 bps
