Square Wave Testing - Audio Amplifier Design

Square Wave Testing Square Wave Testing. Updated 20-Aug-2007. It is perhaps unfortunate that the most common test for stability is to look for 'ringing' on a square-wave test signal. input. The first looks like sustained low level oscillation around 30kHz, while the second looks like damped oscillation at the same frequency. Actually the

However, most common squarewave generators can easily produce harmonics that exceed the response capability of any audio amplifier. By using squarewaves to test equipment it's possible to see a wide range of potential problems, but you need to be able to determine what really is a problem and what is normal behaviour.

The topic of using square waves to test audio products comes up quite frequently. Turns out that it is not a very useful signal for this application due to its nature and how our audio systems work. In this video I explain and demonstrate the signal processing behind square wave and reasons they can be problematic in audio measurements.

This is the best square wave produced by any audio analyzer in the world. The even harmonics are now 110 dB to 120 dB below the fundamental. At 1 MHz, the even harmonics are still 50 dB below the desirable odd harmonics. Intermodulation products and noise are now down at least 130 dB below the fundamental.

After all this, then I look at the square wave, and then usually just at 10kHz into 8 ohms, to check for ringing and slew response. If you want to further check stability, you can parallel the 8 ohm load with a 0.47 to 2.0 uF film cap to see its effect upon the square wave (ie, ringing, overshoot, etc).

Square Wave Testing Sine waves can be used, as has been shown, to check for distortion in audio amplifiers, but a more definite test is afforded by square waves. The effects of square waves can be seen in the diagrams below.. (a) The square wave fed to the amplifier input (b) Waveform distortion of the type given by a differentiator circuit

Since the inception of hemodynamic monitoring, square wave testing, also known as dynamic response testing, continues to intermittently confuse both new and experienced critical care providers. Square wave testing can have a direct impact on the validity and accuracy of the hemodynamic values which are obtained from the invasive monitoring device.
