DSP Blockset

Step 2 -- Get Necessary Blocks.   Place the blocks in the following table into a new model.

Block	Library	Quantity
Digital Filter	Filter Designs (sublibrary of Filters library)	2
Matrix Concatenation	Matrix Operations (sublibrary of Matrices and Linear Algebra library, which is a sublibrary of the Math Functions library)	1
Random Source	DSP Sources	1
Sine Wave	DSP Sources	1
Sum	The Simulink Math library	1
Vector Scope	DSP Sinks	1

Step 1 -- Get the Coefficients of the Predesigned Filters

Step 3 -- Set the Lowpass Digital Filter Block Parameters
