Here, we can easily work out that V1 = VIN ⋅ Z1 Z1+R1 = VIN 1+R1 Z1 V 1 = V IN ⋅ Z 1 Z 1 + R 1 = V IN 1 + R 1 Z 1. Now, we still don't know how to do much with it. But at least it only requires basic knowledge about voltage dividers. It's kind of abstract, still. But the idea is sound.Transfer function of block diagrams | Exercise 1. Starting to study the way to find the transfer function of a block diagram in control systems you can find that you have to reduce by blocks until you have only one block to find the transfer function, this is a bit complicated when you have a block diagram with many components.The transfer function used to find the transient response; The transfer function used to find the sinusoidal steady state response (Bode Plots - frequency response) Transformations to other forms. Since the transfer function is equivalent to the other representations, there must be a way to transform from one representation to another.A decibel (dB) function is typically equal to \(dB(x) = -20\log_{10}(x)\) Understanding that we measure the transfer output on a log scale is very important, and you will see why in a second. Because we measure on this decibel scale, we need to take the \(log_{10}\) of our transfer function.I solved for transfer function in S domain and got the result and I have added it in my question now.

Calculating the natural frequency and the damping ratio is actually pretty simple. If you look at that diagram you see that the output oscillates around some constant value finally settling on it: the frequency of these oscillations is the damped frequency.Hmmmm. So I know through literature that finding the impulse response (which I know is the inverse Fourier of the Transfer Function) of a system requires sending an impulse through the input and to study the resulting output (or as you say sending in a step and studying the resulting output).Example 15-2: Construct the Bode plot for the given transfer function shown in factored form using MatLAB control toolbox functions. 0.001s1 0.001s1 0.005s V(s) V(s) i o Solution: Transfer function has one zero at s=0 and two poles at s=-1/0.001=-1000 Dividing the transfer function denominator and numerator by 0.001 places it
