WS DIGITAL FILTERING ANALYSIS Transfer Function Frequency decimal precision
Hi everybody,
I am a problem with the decimal precision of the Low Cutoff Frequency and the High Cutoff Frequency in the transfer function "band-pass".
If I insert as Low cutoff frequency -> 0.005 and as High cutoff frequency -> 0.008 I have as a result the FIR functions = 0.
checking the log file I get the following:
"The following transfer functions are defined
Transfer 1 - Band pass
Low cutoff frequency : 0.00
High cutoff frequency : 0.00"
Instead if I insert as Low cutoff frequency -> 0.005 and as High cutoff frequency -> 0.012 the log file I get is the following:
"The following transfer functions are defined
Transfer 1 - Band pass
Low cutoff frequency : 0.00
High cutoff frequency : 0.01"
Now the question is: How can I work with low frequencies if the decimal precison is only 2? Is there any way to solve this problem?
Thank you in advance for your replies.
Regards,
