| description | To provide a communication device that restores data from a communication signal transmitted by switching communication speed, and can accurately restore the data without being affected by ringing even if communication speed is switched at high speed.SOLUTION: A communication device includes: a reception unit 32 that samples a communication signal at a predetermined sampling point and decodes communication data; a waveform recording unit 36 that records a signal waveform of the communication signal; and a calculation unit 38. The calculation unit detects a specific bit from the communication data decoded when communication speed is low, acquires the signal waveform of a communication signal corresponding to the bit from the waveform recording unit, and calculates a sampling point of the communication signal at high speed based on the acquired signal waveform and a logical value of the specific bit.SELECTED DRAWING: Figure 4
【課題】通信速度を切り替えて送信されてくる通信信号からデータを復元する通信装置において、通信速度が高速に切り替えられても、リンギングの影響を受けることなく、データを正確に復元できるようにする。【解決手段】通信装置は、通信信号を所定のサンプリングポイントでサンプリングして、通信データを復号化する受信部３２と、通信信号の信号波形を記録する波形記録部３６と、演算部３８を備える。演算部は、通信速度の低速時に復号化された通信データから、特定のビットを検知して、そのビットに対応した通信信号の信号波形を波形記録部から取得し、取得した信号波形と特定のビットの論理値とに基づき、高速時の通信信号のサンプリングポイントを演算する。【選択図】図４ |
