Quickfilter Pro Software Demonstration for QF4A512 The following slides will illustrate how you can design and verify a filter design in minutes! BEGIN Powered by

The Quickfilter Assistant END When you start the program the assistant appears, which can be used to guide you through the design process.

The Quickfilter Assistant END

1. Design a Filter END We will dismiss the assistant by clicking on the icon to design a new filter.

Select Filter Type END The first step is to pick the type of filter. We will choose the basic Parks-McClellan Lowpass

Enter Filter Parameters On this screen we can enter our desired filter specifications: (Sampling f, Passband Upper f, Stopband Lower f, Passband Ripple, and Stopband Attenuation) END

Enter Filter Parameters When we’ve entered the parameters we click “Design”. END

On this screen you can choose your filter type We will select “Lowpass”, then click “Create Filter” View Calculated performance END Software computes number of taps required and plots predicted frequency response…

On this screen you can choose your filter type We will select “Lowpass”, then click “Create Filter” View Calculated performance END …and Impulse Response

Assistant Always Available Notice we can bring back the assistant at any time by clicking here. END

2. Configure the Quickfilter IC END ….and system clock options (if required) For each channel: Specify the filter design to use, the gain, and power / precision options…..

Configure the Quickfilter IC END Software optimizes sample rates for all selected channels. The Configuration is now complete, we can download this configuration and see how it works!

3. Control the Development Board END First, download your configuration to the IC Then, select View FFT

View the FFT of the Actual IC Output The input signal source is from a white noise file, connected to the development kit board from the PC audio output jack. END

View the FFT of the Actual IC Output FFT output views can be a single channel, or up to 4 channels simultaneously. END

View the FFT of the Actual IC Output If a change to the design is desired, the steps can be repeated, and reloaded into the IC within minutes. END

All required cables and software are included in the Development Kit Complete Development Kit Thank you for viewing the demo, return to the website for more details END
