How do you find the transfer function?
To find the transfer function, first take the Laplace Transform of the differential equation (with zero initial conditions). Recall that differentiation in the time domain is equivalent to multiplication by "s" in the Laplace domain. The transfer function is then the ratio of output to input and is often called H(s).
How do you write a transfer function in Bode form?
Bode Form of Transfer Function
Bode form of KG(s) is a factored form with the constant term in each factor equal to 1, i.e., lump all DC gains into one number in the front. 3K(s3+1)4s((s2)2+s2+1)|s=jω=3K4⏟=K0jω3+1jω((jω2)2+jω2+1).
How do you find the value of K in Bode plot?
K = 1.00 so the value of KdB = 20·log10(|K|) = 20·log10(|1.00|) = 0.00. Or, given that KdB = 0.00, |K| = 10Kdb/20 = 100.00/20 = 1. The sign of K depends on phase, in this case K is positive. and phase = 0°.
