Introductionfor granted; for the majority of the modern human population (including some of its highly educated members), this phenomenon still appears to be magical. In order to understand this magic, it is important to review some of fundamental concepts and definitions in physics, mathematics, and engineering.作者: 仔細(xì)閱讀 時(shí)間: 2025-3-22 19:00

Frequency Shifting the process of shifting of lower frequency tone to the upper frequency range (used in RF transmitters), while “down-conversion” refers to the frequency shifting from higher to lower frequency ranges (used in RF receivers). Hence, in a complete wireless communication system, the information-carrying signal is shifted in both directions.作者: FLUSH 時(shí)間: 2025-3-24 22:14
Modulationeast the simplest modulation scheme, based on time divisions, i.e. turning on and off the signal source. By listening to short and long beeps, we can decode complicated messages letter by letter. As slow and inefficient as it is, Morse code does work and is used even today in special situations, for example, in a very low SNR environment.作者: largesse 時(shí)間: 2025-3-24 23:15

Introduction to Frequency Analysis of Amplifiersudes all frequencies, from minus infinity to plus infinity. Nonetheless, we already know that elements capable to store energy need a finite amount of time to change their internal states. For slow changes this time delay is negligible, thus “l(fā)ow frequency” approximation produces acceptable results.作者: gratify 時(shí)間: 2025-3-26 09:00
Electrical Noise“hum” in an audio signal are typical electrical noise manifestations. Noise mainly affects receiving systems, where it sets the minimum signal level that it is possible to recover before it becomes swamped by the noise.

It is based on an underlying mechanism similar to the one used in mixers, where a non-linear element is used to multiply two waves and accomplish the frequency shifting.
