Abstract:
1. A timing detection device comprising: a draw back amount acquiring unit configured to acquire a draw back amount of a received signal with respect to a peak value of the signal; and a detecting unit configured to detect the timing at which the draw back amount acquired by the draw back amount acquiring unit has exceeded a constant value as the timing at which a value of the signal is switched, wherein the draw back amount acquiring unit holds a minimum value and a maximum value of an immediately preceding waveform of the signal, wherein the draw back amount acquiring unit includes an extracting circuit configured to extract a movement of the signal, wherein the detecting unit detects the timing at which the movement extracted by the extracting circuit has exceeded the constant value as the timing at which the value of the signal is switched, and wherein the extracting circuit includes a clamper circuit configured to cancel a DC offset of the signal and extract the movement and a capacitor configured to absorb the DC offset canceled by the clamper circuit.
