Abstract

The digital tuner converts the continuous analog audio signal recorded by the microphone into the sampled digital discrete signal. The digital signal is converted to the frequency using the functions and the nearest tone is determined [1]. Many digital tuners, after sampling the analogue signal, filter out noise and accept sound from a certain level of volume. The result is displayed on the output device, which can be a LED indicator, a display, or a monitor. As a digital tuner can also serve a computer, tablet, or mobile. Our goal was to design and create a digital tuner with myRIO and use the LabVIEW programming environment.
