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.

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 canchoose your filter type

We will select “Lowpass”,then click “Create Filter”

View Calculated performance

END

Software computes number of taps required and plots

On this screen you canchoose your filter type

We will select “Lowpass”,then click “Create Filter”

…and Impulse Response

Assistant Always Available

Notice we can bring back the assistant at any time by clicking here.

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, connectedto 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.
