• Adding another signal

Adding another simulate signal into the block diagram

Setting the signal by adding a Uniform White Noise

• Filtering a Signal

Setting the Filter Express VI

Block diagram of the Analysis VI

Signal with noise

• Modifying the Appearance of the Graphs

Amplitude setting for Unfiltered and Filtered signals

Time setting for Unfiltered and Filtered signals

Amplitude scales setting for both signals

The appearance of both signals after modifying process.

• Analyzing the Amplitude of the Signal

Peak to peak value setting

• Controlling the Speed of Execution

Time delay setting to 1 sec

The movement of the both signals move more slowly

• Adding a Warning Light

Block diagram of warning light included

Front panel when warning light is included

The warning light will on if the peak exceed the limit value of 2

• Setting a Warning Level Limit

Setting the Level Limit to the >Greater

• Configuring a VI to Save Data to a File

Write to Measurement File setting

The data collected is displayed via Notepad

 

CHAPTER 2

• By using Mean

 Figure 3: When enable off only white sine wave produce without mean value












• By using Table
