Unformatted text preview: And the block diagram of this RLC device is like this: Figure 1: The RLC Block Diagram The transfer function and the equation for the RLC circuit are: The transfer function: 2 2 2 2 ) ( n n n s s s G ϖ ζϖ ϖ + + = ( 1 ) The natural frequency: LC n 1 2 = ϖ ( 2 ) The damping ratio: L C R 2 = ζ ( 3 ) 4) THE EXPERIMENT In this experiment we firstly set up the circuit, which is given in Figure 1 and we connected the circuit to the oscilloscope that the input is displayed on CH1 and the output is displayed on CH2. Than we determined the step input response by these steps: i) We first switch the waveform to square wave and adjust the frequency to a low value. Then we placed the input signal in the middle of the screen. ii) We changed the R, L and C values to see the effects of each parameter on the system response such as oscillations, steady-state error, etc. after getting a good reasonable step response we stopped changing the R, L and C values. The values for the R, L and C are: R=10 kΩ...
