DSP Blockset

Step 4 -- Set the Highpass Digital Filter Block Parameters.   Set the other Digital Filter block with the same settings as shown in Figure , except change the Numerator coefficients parameter to hipassNum; this block implements the highpass filter that outputs the high-frequency noise.

Step 3 -- Set the Lowpass Digital Filter Block Parameters

Step 5 -- Set the Rest of the Blocks' Parameters and Connect the Blocks
