Zusammenfassung:PURPOSE:To easily measure an error rate characteristic of a MODEM or the like with a small scale and simple circuit constitution by designing a pattern so as to avoid bit delete in at least one channel. CONSTITUTION:A bit delete pattern 43 is constituted to be a pattern not applying bit delete for at least one channel and a punctured code generated by using the bit delete pattern 43 is used to test an error rate. Thus, an output code of a channel not applying bit delete in the output code of a dummy bit transmission circuit 46 at a receiver side is compared with a prescribed pseudo noise series code as it is to obtain an error rate.
