    • A signal processing apparatus (11) is configured to process a signal transmitted via a transmission path where a waveform representing the signal value of a particular symbol is distorted in accordance with values of symbols transmitted prior to the particular symbol, and includes the following elements: a receiving unit (16) configured to receive a test signal including symbols set to predetermined values via the transmission path; an obtaining unit (25) configured to obtain the signal value of a particular symbol from the test signal received by the receiving unit (16); and a characteristic computing unit (27,28) configured to compute a characteristic of distortion on the basis of waveforms represented by signal values obtained by the obtaining unit (25) from a plurality of test signals.
    • 信号处理装置(11)被配置为处理经由传输路径发送的信号,其中表示特定符号的信号值的波形根据在特定符号之前发送的符号的值而失真,并且包括以下元件: 接收单元(16),被配置为经由传输路径接收包括设置为预定值的符号的测试信号; 获取单元(25),被配置为从所述接收单元(16)接收的测试信号中获得特定符号的信号值; 以及特征计算单元(27,28),被配置为基于由所述获取单元(25)从多个测试信号获得的信号值表示的波形来计算失真的特性。
