Hi Marie,
The block shown in the image represents a transfer function. There are multiple blocks in Simulink that can serve this purpose. Here are two options you can consider:
- Transfer Fcn Block: This block allows you to specify a transfer function using its numerator and denominator coefficients. More details can be found in the following documentation: https://www.mathworks.com/help/simulink/slref/transferfcn.html
- Zero-Pole Block: This block lets you specify a transfer function in terms of its zeros, poles, and gain. More information is available in the following documentation: https://www.mathworks.com/help/simulink/slref/zeropole.html
I hope this helps!
