The bilinear transform is employed in digital signal processing and discrete-time control theory which helps in transforming continuous-time system representations to discrete-time
The bilinear transform (also known as Tustin's method) is usually applied in digital signal processing and discrete-time control theory. It is used to transform continuous-time system representations into discrete-time and vice versa.
This transform usually preserves stability and also maps every point of the frequency response of the continuous-time filter.
The answer is B because it could be feasible but it’s not a need it and you got a time frame but it’s not a requirement and it doesn’t have to be unique.
