Space vector modulation (SVM) is an algorithm for the control of pulse-width modulation (PWM), invented by Gerhard Pfaff, Alois Weschta, and Albert Wick in 1982. [1] [2] It is used for the creation of alternating current (AC) waveforms; most commonly to drive 3 phase AC powered motors at varying speeds from DC using multiple class-D amplifiers.
Versions of Excel up to 7.0 had a limitation in the size of their data sets of 16K (2 14 = 16 384) rows. Versions 8.0 through 11.0 could handle 64K (2 16 = 65 536) rows and 256 columns (2 8 as label 'IV'). Version 12.0 onwards, including the current Version 16.x, can handle over 1M (2 20 = 1 048 576) rows, and 16 384 (2 14, labeled as column ...
[7] On the contrary, delta modulation and delta-sigma modulation are random processes [ clarification needed ] that produces a continuous spectrum without distinct harmonics. While intersective PWM uses a fixed period but a varying duty cycle, the period of delta and delta-sigma modulated PWMs varies in addition to their duty cycle.
Microsoft's version of Wordpad included with Windows 7 supports opening and saving in the docx format. [22] The Mac OS X-based NeoOffice office suite supports opening, editing, and saving of most Office Open XML documents since version 2.1. [23] Nisus Writer Pro has built-in, but rather limited, support for opening OOXML documents.
Besides differences in the schema, there are several other differences between the earlier Office XML schema formats and Office Open XML. Whereas the data in Office Open XML documents is stored in multiple parts and compressed in a ZIP file conforming to the Open Packaging Conventions, Microsoft Office XML formats are stored as plain single monolithic XML files (making them quite large ...
