能量信号与功率信号(Energy Signal & Power Signal)2021-04-23 10:50:34 2614 定义 能量有限信号,简称能量信号;功率有限的信号,简称功率信号。 将信号施加到1Ohm的电阻上,它所消耗的瞬时功率为,在区间的能量和平均功率定义为: 信号能量: 信号功率: 如果信号 的能量有界,即,则称其为能量有限信号,简称能量信号...
energy signal:能量信号,若信号f(t)的能量有界,及E 数字信号中的energy signal 和power signal的区别 energy signal:能量信号,若信号f(t)的能量有界,及E<∞,则称其为能量有限信号,简称能量信号,此时P=0 结合能(binding energy)和吸附能(adsorption energy)的区别 结合能(binding energy)是指当一“物体(体系)...
energy signal：能量信号，若信号f(t)的能量有界，及E＜∞，则称其为能量有限信号，简称能量信号，此时P=0；power signal：功率信号，若信号f(t)的功率有界，及P＜∞，则称其为功率有限信号，简称功率信号，此时E=∞
energy signal 是能量信号，power signal 是动力信号，有了power signal 后才可以谈 energy

The probability of transmission error is determined by the signal-to-noise ratio (SNR) at the receiver, which is proportional to the transmitted bit energy and inversely proportional to the distance between transmitter and receiver to the power of the path loss exponent (SNR∼Et/dκ). The onl...
These results, however, apply in steady state11 and it is independent receptor that maximise the signal-to-noise ratio under a finite integration time14,15 even when receptor interactions are coupled to energy consumption16. More generally, a trade-off exists between noise-reduction and available ...
