Encoder Resolution
Compute the angular resolution of an incremental rotary encoder, R = 360°/PPR, dividing 360° by the pulses per revolution (PPR). It is the smallest angle increment the encoder can distinguish — the more pulses per turn, the finer the position measurement. A 3600-PPR encoder resolves 0.1° per pulse. The basis of position control in servomechanisms and CNC. Enter the pulses per revolution.

Resolução de encoder
Um encoder rotativo incremental mede ângulo gerando pulsos elétricos conforme o eixo gira. A resolução angular é o menor ângulo que ele distingue: R = 360°/PPR, onde PPR é o número de pulsos por rotação. Um encoder de 360 PPR resolve 1° por pulso; um de 3600 PPR, 0,1°; modelos de alta precisão chegam a milhares de PPR. Com a técnica de quadratura (dois canais defasados 90°), a resolução efetiva quadruplica e ainda se obtém o sentido de rotação. É o coração do controle de posição em servomotores, CNCs, robôs e telescópios — onde saber a posição exata do eixo é tudo. Informe o número de pulsos por rotação.

ADC Resolution
Compute the resolution of an analog-to-digital converter (ADC), R = FSR/2ⁿ, dividing the full-scale range (FSR, in volts) by the number of levels (2 to the power of the number of bits). It is the smallest voltage step the converter distinguishes — the more bits, the finer the resolution: a 12-bit ADC divides the range into 4096 levels. Fundamental in data-acquisition and digital-instrumentation design. Enter the full-scale range and the number of bits.

Linearity Error
Compute the linearity error (non-linearity) of an instrument, LE = (maximum deviation/span)·100%, the largest departure of the actual curve from the ideal straight line, expressed as a percentage of span. It measures how much the instrument's response deviates from a straight line — the smaller, the more 'linear' and predictable the reading. It is one of the components of specified accuracy. Enter the maximum deviation and the instrument span.
Skip Distance (Angle-Beam Ultrasonics)
Computes the skip distance of an angle-beam ultrasonic test, S = 2 × t × tan(θ), the surface distance between the beam entry point and the point where it returns to that same surface after bouncing off the back wall. It is what sets the operator's scanning band: to cover the full thickness of a butt weld the probe must sweep between half a skip (t × tan θ, where the beam reaches the back wall) and a full skip. Larger angles stretch the skip and move the probe away from the bead, which helps when the weld cap cannot be ground off, but they also lengthen the sound path and increase attenuation. Enter the part thickness and the probe refracted angle.
