Absolute Encoders - Ab.rockwellautomation.com
Bulletin 842HR Sine/Cosine is a 15-bit serial encoder for high performance digital servo drive systems that require absolute feedback for position control, and high resolution incremental feedback for speed control. This encoder provides commutation, speed regulation, and position control all in one device. ... Retrieve Document

Optical Encoders - NYU Tandon School Of Engineering
Optical Encoders K. Craig 23 • The larger of the two resolutions governs the displacement resolution of the encoder: • The physical resolution of an encoder can be improved by using step-up gearing so that one rotation of the moving object that is being monitored corresponds to several rotations of the code disk of the encoder. ...

Incremental Encoder - Wikipedia
An incremental encoder is a linear or rotary electromechanical device that has two output signals, A and B, which issue pulses when the device is moved. Many incremental encoders have an additional output signal, typically designated index or Z, which indicates the encoder is located at a particular reference position. ... Fetch This Document

Determining Pulses Per Revolution For An Encoder Application
To avoid this, choose an encoder whose PPR is an even multiple of the value that is being measured. For example, if one revolution of the encoder equals 12 inches, choose a 1200 PPR encoder. Speed. Another important factor in determining the required pulses per revolution is the encoder’s maximum speed—both mechanical and electrical. ... View This Document

Encoder Resolution And Accuracy: What's The Difference?
The higher resolution encoder just has the ability to break up that 90 degree movement into much smaller increments. Factors that affect resolution. An encoder’s resolution is based on the number of lines (for an incremental encoder) or the pattern (for an absolute encoder) on the encoder disk or scale. Physically, resolution is fixed. ...

Windows Media Audio - Wikipedia
Windows Media Audio. Windows Media Audio (WMA) is the most common codec of the four WMA codecs. Colloquial usage of the term WMA, especially in marketing materials and device specifications, usually refers to this codec only. The first version of the codec released in 1999 is regarded as WMA 1. ... Read Article

DTS-HD Master Audio - Wikipedia
DTS-HD Master Audio supports variable bit rates up to 24.5 Mbit/s. The format supports a maximum of 192 kHz sampling frequency and 24-bit depth samples from 2 to 5.1 channels, and 96 kHz/24bit resolution up to 7.1 channels. DTS-HD Master Audio is capable of virtually any number of discrete channels but is limited by storage media. ... Read Article

What’s An Encoder’s PPR, CPR, And LPR? | CUI Inc
By observing the changing states of the A and B outputs the encoder’s direction can be determined. Typical encoder square wave outputs A and B. However, to determine the distance an encoder has traveled, or at what speed it is rotating, more information is required. To calculate this information it is important to know the encoder’s resolution. ... Visit Document

Thus, a 12-bit encoder has a resolution of 4,096 points. Accuracy (unlike resolution) depends in whole-system interations with the application, and is traceable to the encoding disc (a ... Retrieve Doc

How To Calculate Encoder Resolution - Linear Motion Tips
If the encoder uses X2 or X4 encoding, the encoder’s required PPR should be divided by a factor of 2 or 4, respectively. For example, if the application calls for an encoder that has a resolution of 2500 PPR, but X4 encoding is being used, then the encoder’s actual resolution only needs to be 625 PPR (2500 ÷ 4). ...

High Resolution Encoder - Zettlex
A high resolution encoder is typically a rotary or angle encoder with a resolution of >10,000counts per revolution (cpr) and often >100,000cpr. For incremental encoders, with A/B pulse style outputs, resolution is specified as 4x the number of pulses per rev since there are 2 edges to be counted ... Return Doc

Rotary Encoder - Wikipedia
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.. There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle transducer. ... View Document
