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).

• The error function erfc is used to calculate the probability of bit error.

• The formula for calculating the probability of bit error is P = 1/2 * e

Q2. Explain what are GANs?
Ans. 
GANs are Generative Adversarial Networks, a type of deep learning model consisting of two neural networks - a generator and a discriminator.
• GANs are used to generate new data samples that resemble a given dataset.

• The generator network creates fake data samples, while the discriminator network tries to distinguish between real and fake samples.

• The two networks are trained simultaneously in a competitive manner, improvin...read more

Q4. Explain working of Neural networks?
Ans. 
Neural networks are a type of machine learning algorithm inspired by the human brain's neural structure.
• Neural networks consist of layers of interconnected nodes (neurons) that process input data and pass it through activation functions.

• They use weights to adjust the strength of connections between neurons during training.

• Neural networks are capable of learning complex patterns and relationships in data, making them su...read more
