This contribution describes design methodology and implementation of a single-chip timing and carrier synchronizer and channel decoder for digital video broadcasting over satellite (DVB-S). The device consists of an A /D converter with AGC, timing and carrier synchronizer with matched filter, Viterbi decoder including node synchronization, byte and frame synchronizer, convolutional de-interleaver, Reed Solomon decoder, and a descrambler.The system was designed in accordance with the DVB specifications. It is able to perform Viterbi decoding at data rates up to 56 Mbit /s and to sample the analog input values with up to 88 MHz. The chip allows automatic acquisition of the convolutional code rate and the position of the puncturing mask. The symbol synchronization is performed fully digitally by means of interpolation and controlled decimation. Hence, no external analog clock recovery circuit is needed.For algorithm design, system performance evaluation, co-verification of the building blocks, and functional hardware verification an advanced design methodology and the corresponding tool framework are presented which guarantee both short design time and highly reliable results. The chip has been fabricated in a 0.5 µm CMOS technology with three metal layers. A die photograph is included.

December, 2014 A few days ago we shared with you a set of useful tips to help you integrate Twitter in your instruction. Today, we have come across this wonderful rubric created by University of Wisconsin that can be a very good addition to the resources we have been featuring here on the educational use of Twitter. This rubric is designed specifically to help teachers assess students' Twitter use in instructional assignments. It focuses on five key areas: 1- Content This one evaluates the content of students' tweets and whether these tweets add value to the classroom discussion or not. 2- Frequency This one assesses the frequency of students' tweets: whether it exceeds the required number of tweets per week or not. 3-Hyperlinks This category is about the quality of the links embedded in students' tweets: are they relevant to the topic, do they enhance it..etc 4-Mechanics Tweeting is also a form of writing and as such this category assesses the mechanics of writing in students' tweets. It covers things such as grammatical errors, use of capitalization, punctuation and spelling. 5-Comments and Contributions This one assesses how students communicate, interact and respond to each other's tweets. This rubric is available for free download in PDF format from this link. Follow us on : Twitter, Facebook , Google plus, Pinterest .
