Hello, I was given a block diagram for homework and I was asked to find the transfer function. I found the transfer function but I would like to test its response to ensure that block diagram simplification was done properly. I would like to make a single block and enter all parameters to compare the responses. Simulink has some transfer function blocks but I don know how to enter *s* in the denominator. Any help would be appreciated.

Hi. If you are using a Transfer Fcn block and have the coefficients defined in your workspace, then enter the equations in the block as shown below. The result transfer function will appear as shown.

Thankyou. This is exatcly what I was was looking for. I didn't know how to enter more coefficients and varibles the numerator/denominator of block. I couldn't find any example in the web.
