With Moku:Lab’s FIR Filter Builder, you can design and implement lowpass, highpass, bandpass, and bandstop finite impulse response (FIR) filters with up to 14,819 coefficients. Moku:Lab’s iPad interface allows you to fine-tune your filter’s response in the frequency and time domains to suit your specific application. Select between four frequency response shapes, five common impulse responses, and up to eight window functions.

Features Specifications
  • Visualize your signal and configuration in real-time: design filters in the time domain or in the frequency domain
  • Visualize the filter’s transfer function, impulse and step response, or group and phase delay
  • Block diagram view of the digital signal processing with built-in probe points for signal monitoring
  • Load your own filter coefficients or enter an equation to create a customized impulse response
  • Independent channels: 2
  • Coefficient count at various sampling rates:
    2 to 232 @ 15.63 MHz
    2 to 928 @ 3.906 MHz
    2 to 3712 @ 976.6 kHz
    2 to 14819 @ 244.1 kHz
  • Filter coefficient precision: up to 24 bits
  • Design domains: time (impulse response), frequency (frequency response)
  • Impulse response: rectangular, since, equation input, custom, etc
  • Frequency response: lowpass, highpass, bandpass, bandstop

What's New?

We’ve recently refreshed our website, and we hope that you will find the changes to be a big improvement. We’ve worked hard to make it easier to navigate the site, and to find exactly what you need from among our vast and diverse range of products.

Missing e-commerce?

One thing that we’ve not carried over from the previous site at this time is the facility to order online for a select range of our products, which you may have been used to in the past. “Off-the-shelf” items represent a small part of our product range; most often a purchase requires a more in-depth discussion between our sales team and the customer to match the right product to the user’s application. For this reason we have focussed on making it as easy as possible to request a quotation from our sales team.

Please rest assured that we will get back to you with pricing promptly, and will work with you to make sure the products you buy are exactly what you need. Once you’re ready to order, our sales team will work through the process with you, to make it as seamless as possible.

Once you’ve selected all the items you’re interested in, by clicking “Add to Quote” on the product page, just click “View Quote Request List” or the icon in the top navigation bar, check your list, set quantities, complete your details and submit the form. Our sales team will respond by email, in a timely manner.

If you have any other questions in the meantime, please get in touch directly.
