Answer 1

Digital modulation(or channel encoding)is the process of converting an input sequence of bits into a waveform suitable for transmission over a communication channel.Demodulation(channel decoding)is the corresponding process at the receiver of converting the received waveform into a (perhaps noisy)replica of the input bit sequence.

数字调制（或信道编码）是将比特输入序列转换为适于在通信信道上传输的波形的过程。解调（信道解码）是将接收到的波形转换为输入比特序列的（可能是噪声）副本的接收波形的相应处理过程。

Answer 2

电子调制（或者信道编码）是将输入的比特序列转化为可以通过通讯渠道传输的波段的过程。解调制（指着信道解编码）是将收到的波段转化为比特序列的副本（可能是杂音）的相对过程。
