One of the most important characteristics of moral judgments is that they express our values. Not all expressions of values are also moral judgments, but all moral judgments do express something about what we value.
Several factors affect noise. 1  Pixel size. Simply put, the larger the pixel, the more photons reach it, and hence the better the signal-to-noise ratio (SNR) for a given exposure. The number of electrons generated by the photons is proportional to the sensor area (as well as the quantum efficiency).
A commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor.
