Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test Setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test Set-up totheir limits. A method for accurate measurement of thirdorder intermodulation products, IM3, with standard testequipment is outlined below.It is also important to correctly interpret the LT5514specification with respect to ROUT, and the impact ofdemo-board transmission-line termination loss whenevaluating the linearity performance, as explained in theLT5514 Datasheet and in Note 1 of this document.
介紹幾種cpuThe 8xC251SA/SB/SP/SQ improves on the MCS-51 architecture and peripheral features, introducing the advanced register based CPU architecture i.e., the MCS 251 microcontroller architecture. The register based CPU supports a 40-byte register file. In addition, the 8xC251SA/SB/SP/SQ microcontroller has 256-Kbyte expanded external code/data memory space and 64-Kbyte stack space. The new controller is also specially designed to execute C code efficiently. More importantly, the 8xC251SA/SB/SP/SQ maintains binary code compatibility with MCS 51 microcontrollers but at the same time allows the use of the powerful MCS 251 microcontroller instruction Set, with many new 8, 16 and 32 bit instructions available. The 8xC251SA/SB/SP/SQ has 512 bytes or 1 Kbyte of on-chip data RAM options and is available in 16 Kbytes and 8 Kbytes of on-chip ROM/OTPROM or ROMless options.
基于matlab的mp3的讀寫函數(shù)Mp3 toolbox for Matlab. Alfredo Fernandez Franco Aalborg University Departament of Acoustics M.Sc. Student aberserk@yahoo.com Includes 2 functions to write and read MP3 files. It works like the commands WAVWRITE and WAVREAD. 1.- Just unpack in the toolbox folder under the MATLAB directory. 2.- Set the MATLAB search path to include that folder. This version was made in MATLAB for WINDOWS only. I ll probably will make the UNIX version later. 01-11-2004.
