Q1. Probability of bit error in a binary symmetric channel
Ans. 
The probability of bit error in a binary symmetric channel can be calculated using the formula P = 1/2 * erfc(sqrt(Eb/N0)), where erfc is the complementary error function.
• Probability of bit error in a binary symmetric channel is influenced by the signal-to-noise ratio (Eb/N0).
