With most switch CARDS, there will be some small capacitance between adjacentchannels.
对于大多数开关卡,相邻通道间都具有小的电容。
2
Because capacity of channel is limited by interference. Especially for the interference from the same channels and the adjacentchannels.
由于信道的容量是由干扰所限定的,尤其是同信道干扰和邻信道干扰的影响更为严重。
3
Amplifier distortion produces a dilation of the spectrum of the input signal (" spectral regrowth ") which causes interference to communications in adjacentchannels.
