Hi Fred, thanks for your reply.The approch is good but the problem f the sawtooth wave step response.As explained before I've realized the...
Hi Rick, that was one of the first attempts, unfortunately I've to filter both odd and even multiple of the fondamental. Best regards
As explained before the signal s(t) to be analyzed is a random process with spectrum support
within [0..1 kHz]. Grid harmonics are summed to this signal up to the...
"I am a firm believer that the easiest signal processing is the signal processing that you don't have to do!"Let's put that one in a frame ! :)
I try to answer to your questions:Does the desired AC signal consist of single or multiple frequencies? The signal s(t) to be analyzed is a random process with...
The best algorithm for achieving what you want (of which I am aware) is called the "shielded cable algorithm." :)Cables in the plant are shielded. :)At first......
Is the 50 Hz a power main signal? Yes, but consider that frequency is not fixed but time variable. Alarm condition are signaled outside limits [49.9 - 50.1] Hz....
The sampling rate is about 3kHz and we are trying to attenuate both odd and even harmonics.The harmonics can extend a lot into the spectrum ( up to 700-800 Hz ).The...
I'm facing a problem trying to filter 50Hz and harmonics from a signal s(t).I've implemented several techniques like Kalman filtering, optimized FIR and IIR filters...
@stephaneb I've filled all the required fields but they are blinking changing the focus continuously.I've tried by using 3 different...
