Ways to smoothen signals

[Isabella]

Hi All,

My program DAQ input from my labview reads a wide range of values. From negative milivolt to 0.435volt for example. Is there any way to smoothen the signal? Currently, I'm using the 'collector & statistics'. Every time I change my collector-max number of samples by increasing it, the values is almost like 20-21 Degree Celsius.

Is there any other way to smoothen signals? Thank You.

Regards,

Isa

When you say "smoothen" do you mean to reduce noise on the signal? If so, there are a number of techniques. One method that is easy to implement is a 3-point running median.
