Signal Processor Board Functions  

•

 

Receives the optical signal reflected off the bar code. 

•

 

Converts received optical signal into electrical signal (current) of about 100 nanoamps. 

•

 

Converts the electrical signal (current) to a suitable voltage signal level for the Decode board. 

•

 

Discriminates and filters out all unwanted signals and noise.
