Swept sine waves let you test a device over a wide frequency range. To implement a swept sine wave with a multifunction data-acquisition card, you need to generate the data points and send them to the ...

Analog-to-digital converters (ADCs) sample analog signals and produce a value that corresponds to a “snapshot” of the signal at a specific time. By taking samples at regular intervals, you can obtain ...

Sine-wave speech can be thought of as a sort of auditory illusion, a sensory edge case in which one’s experience has a clear “before” and “after” moment, like going through a one-way door. Sine-wave ...

Select between the Combination or Sequential circuit for analysis (Figure 16). Figure 16: Screen to select Combinational or Sequential Circuit Select the number of inputs (max of 3) and number of ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio ...

This simple design produces a sinewave that ranges from 2Hz to 20Khz using a CypressMicro PSoC chip. More information on these versatile devices can be found on their web page at: If we set f to 1Khz ...

The AUSampler software instrument (included with Garage Band) has a built-in A-440 tone. I'm not at a computer that I can test it on right but if you select that and nothing else (no other sample ...

Your mission, should you choose to accept it, is to build a three-part beat using only a single raw waveform. Let’s go… Step 1: The sine wave is the raw building block of sound, of which all other ...
