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

Q1. What is gd&t and application
Ans. 
GD&T stands for Geometric Dimensioning and Tolerancing. It is a system for defining and communicating engineering tolerances.
• GD&T is used to specify the allowable variations in form, size, and orientation of part features.

• It uses symbols, such as concentricity, flatness, and perpendicularity, to communicate design requirements.

• GD&T ensures that parts fit together properly and function as intended.

• It is commonly used in...read more

Q2. What cop of refrigeration
Ans. 
The question seems to be asking about the COP (Coefficient of Performance) of refrigeration systems.
• COP is a measure of the efficiency of a refrigeration system, calculated as the ratio of cooling output to the energy input.

• A higher COP indicates a more efficient system.

• For example, a heat pump with a COP of 3 can provide 3 units of heating for every 1 unit of electricity consumed.
