U8903A Audio Analyzer by using the MATLAB software on your computer. Steps to create a custom filter Follow the steps below to create your own custom filter for the U8903A. Steps 1. Matlab fdatool (filter design and analysis tool) 2. Create Filter 3. Export Filter Coefficient 4. Settling Time (Delay) 5. Transfer to .juf file 6. Upload .juf file to U8903A Audio Analyzer 2 Step 1 Matlab fdatool (Filter Design and Analysis Tool) Instructions 1. Start MATLAB program (Figure 1) 2. In the command window, type "fdatool" to start Filter Design and Analysis Tool in MATLAB (Figure 2) Figure 1. MATLAB command window Figure 2. Filter Design and Analysis Tool 3 Step 2 Create filter Instructions 1. Click on "Set quantization parameter" (Figure 3) 2. Select "Single-precision floating-point" because the architecture of the U8903A is 32 bits (Figure 4) 3. Return to the Design Filter page (Figure 4) Figure 3. "Set quantization parameter" icon Figure 4. Selecting "Single-precision floating-point" and "Return to the Design Filter page" 4 Instructions 4. Select the "Response Type" e.g. Lowpass, Highpass, Bandpass, and Bandstop (Figure 5) 5. Select the "Design Method" e.g. IIR or FIR (Figure 5) 6. Select the "Frequency Specifications" you require e.g. Fpass (1 and 2), Fstop (1 and 2) (Figure 5) Requirements for Frequency Specifications:
