Unraveling the PPG Wave 2.2 & 2.3: An 8-bit vs. 12-bit DAC Mystery

2024-12-15

This article delves into the subtle yet significant differences between the PPG Wave 2.2 and 2.3 synthesizers. While the 2.3 utilizes 12-bit DACs, wavetable playback remains 8-bit; only samples imported via external devices fully leverage the 12-bit precision. Oscilloscope measurements reveal a unique audio processing method: two oscillators send data interleaved, resulting in a DAC output frequency double the individual oscillator sample rate. This creates a distinctive timbre and high-frequency aliasing beyond human hearing. The article also notes the relatively slow CV update rate, yet the sound retains its character.

Sensirion SGP41 TVOC Sensor Accuracy Test: Relative Changes, Not Absolute Values

AirGradient conducted accuracy and precision tests on the Sensirion SGP41 TVOC sensor used in their air quality monitors. The tests revealed that the sensor effectively tracks relative changes in TVOC levels – detecting increases or decreases – but cannot provide precise absolute values. This is due to limitations inherent in low-cost VOC sensors, including lack of specificity, cross-sensitivity, environmental sensitivity, and baseline drift. While the sensor cannot precisely measure TVOC concentrations, it still offers practical value in identifying TVOC sources and for environmental monitoring. Future testing by AirGradient will explore sensor performance under various conditions to further understand its capabilities and limitations.
