PWMとアナログ制御の違いがあるとしたら、PWMの方が、回路は簡単、スイッチ素子のトランジスタの損失が小さくて済む、ってことだよね。 0444774ワット発電中さん2018/03/07(水) 19:23:45.48ID:izLA8fGyhttps://www.digikey.jp/ja/articles/techzone/2012/sep/digital-dimming-solves-led-color-dilemma References "The Current-Voltage Characteristics of an LED and a Measurement of Planck's constant," University of Connecticut, Department of Physics.

The quicksort algorithm is well known and readily available from libraries for software developers writing general-purpose applications in C++ or Java, but some Javascript implementations do not provide this specific algorithm. Hence, if a developer wants to reliably use quicksort on their web page, they must "reinvent the wheel" by reimplementing the algorithm. They could conceivably copy it from another web page, but then they could run into copyright and software licensing issues. Reinventing the wheel in this case provides the missing functionality and also avoids copyright issues.
Additionally, those new to a language (and especially those new to programming) will often attempt to manually write many functions for which a more robust and optimized equivalent already exists in the standard library or other easily available libraries.[citation needed] While this can be useful as a learning exercise, when done unknowingly the result is often less readable, less reliable and less optimized software which takes longer to write, test, maintain, and debug.
