求翻译：由于信道的不理想，再加上存在噪声，接收滤波器收到的波形与发送端发出的波形可能差别比较大，如果马上进行判决，可能产生较多的误码，因此，在取样判决之前需先经过一个接收滤波器，一方面滤除带外噪声，提高信噪比，另一方面对失真的波形进行均衡，因此，接收滤波器中还应包括均衡器在内，以便得到有利于取样判决的波形是什么意思？

As the channel is not ideal, coupled with the presence of noise, the receiver filter and the transmitter waveform received waveform may be issued by relatively large differences, if immediate decision, may produce more errors, therefore, required before the sample sentence go through a receiver filt

Because the channel is not ideal, in addition has the noise, the profile possible difference which receives which the filter to receive the profile and the transmitting end send out quite to be big, if carries on the decision immediately, possibly has many error codes, therefore, before sample decis
