    Bit resolution and sampling rate are two of the most important characteristics of an analog-to-digital converter (ADC). With a higher bit resolution, the input signal can be digitized with a higher resolution and lower quantization noise. Therefore, it helps improve the overall outcome of the entire digital signal processing (DSP) workflow. Most ADCs are designed…

    Raman effect was first discovered in the 1920s by C.V. Raman1, 2. It is a widely used spectroscopic method to determine the vibrational modes of molecules3, 4. Compared to other analytical chemistry methods, spectroscopic approaches provide high spatial resolution. No direct contact is required to obtain chemical information. The vibrational spectrum offers reasonable chemical specificity…

    Updated April 24, 2023 In this application note we describe the use of the Moku Data Logger to capture a high-speed mechanical impact using a strain gauge. We are aiming to drop a steel ball onto an aluminum plate, measure the strain of this roughly 100 ms event, and observe any resulting mechanical oscillations. In…

    In this application note we provide a tutorial using Moku:Lab’s Arbitrary Waveform Generator with MATLAB. Step-by-step instructions are detailed for deploying two simple waveforms from MATLAB directly to Moku:Lab. We use a second Moku:Lab running the Oscilloscope and Spectrum Analyzer instruments to confirm the output waveforms. A Lissajous curve example is then shown together with…
