Real-time Filtered Channel (ID=7027)

A Finite Impulse Response ( FIR) filter is employed to tune the frequency response of a specified channel, to design your own low-pass, high-pass,  band-pass or notch filters





  • A Finite Impulse Response ( FIR) filter is employed to create low-pass, high-pass,  band-pass or notch filters

  • Analog frequency adjustors like the frequency band equalizer of an audio amplifier. Note. the scroll bars represent the attenuators for the primary frequencies, where the maximum is 100% and the minimum is 0%, and the frequencies in the actual waveform that are not a primary frequency will not be completely filtered out.

  • Channel number is a 0-based index to Windaq's scanlist. For example, if Windaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.

  • Intelligent Channel Select: Highlight/Select a channel in Windaq and fire up this Windaq add-on, and it will use the selected channel as its default channel

  • Retainable frequency response

  • Sizable Chart and Equalizer display

  • To restore full dynamic range of the chart, double click on the min/max notation next to the chart

  • Note: Limitations of digital filters can be expected, such as leakage and delay

  • Bonus for users with paid registration :

    • No ad-line in the chart

    • No time limit

To Use WinDaq Add-ons

  1. Confirm WinDaq 3.16 or higher is installed on your computer

  2. Install WinDaq add-ons.

  3. Restart WinDaq, and you will find the WinDaq add-ons integrated into Windaq->View->Add-ons menu (see the screen capture above).

  4. Intelligent Channel Selection: Highlight/Select a channel in WinDaq and fire up the WinDaq add-on you wish, and the WinDaq add-on will use the selected channel as its default channel. 

  5. If channel index number is required for a WinDaq add-on, please enter the 0-based index to Windaq's scanlist. For example, if WinDaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.

  6. Do not change WinDaq's configurations while WinDaq add-ons are running, or some add-ons may terminate.
