Optimization of Signal-to-Noise Ratio in Linear Systems,f objective lenses largely restricted the performance of those early telescopes. In the latter half of the 17th century, the Huygens brothers recognized that long focal lengths were less susceptible to aberrations. That recognition inspired telescopes with 30- to 60-meter focal lengths, but such ext名字 发表于 2025-3-27 06:41:32

This process is generally called . and the devices that change the signal’s spectrum are traditionally called ..流行 发表于 2025-3-28 01:30:04

The observation itself is not obvious at all and, of course, the key to applying it is in the details: In what is sense the approximation meant? What is the precise algorithm for obtaining such an approximation?袭击 发表于 2025-3-28 05:24:18

All of the results written in the complex form can be translated quickly into results for real trigonometric series expressed in terms of sines and cosines via de Moivre’s formula .. = cos . + . sin ., familiar from Chapter 1.
