WebApr 2, 2024 · Signal-to-noise ratio (SNR) is a generic term which, in radiology, is a measure of true signal (i.e. reflecting actual anatomy) to noise (e.g. random quantum mottle).A lower signal-to-noise ratio generally results in a grainy appearance to images. In radiography, the signal-to-noise ratio, and thus the apparent noisiness of the image, is proportional to the … WebJun 6, 2024 · The datasheet for the op-amp specifies that I should compensate the MAX40089 (my dual op-amp of choice) when dealing with gains of 10+, putting a capacitor in parallel with the inverting feedback resistor with gain multiplied by 10 pF. For compensation, I thus place 220 pF SMD film caps on the (-) feedback resistors on both …
