The integrated 1/f noise is proportional to ln(fh/fl), where fl is the lower limit for integration, and fh is the upper limit. So,for real application,how to determine fl?

For general consideration, you can fl=0Hz. For equiment measure, it is 100Hz usually.

Not really a good idea for calculating ln(fh/fl) :!: :roll:

fl depends rather much on the used (input) device(s) and the circuit method.
Usually in the range 10Hz .. 10kHz .
