IPC: H04B10/00
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a data receiving device which increases the transmission speed, without producing erroneous detection even if it receives data which includes data whose '0' continues over a long time, such as image data. SOLUTION: A sampling and holding circuit 514 is provided, which can selectively output a threshold signal 5132 outputted from an ATC circuit 513 to a comparator 515 as it is as a threshold signal 5141 according to a hold signal 556 or output it after holding its voltage.
