ABSTRACT:
A receiving apparatus which suppresses threshold-voltage changes. A peak voltage detection block detects the peak voltage of a signal. A bottom voltage detection block detects the bottom voltage of the signal. A stop control block generates a stop signal for stopping the operations to detect the peak voltage and the bottom voltage. A threshold value specification block specifies a threshold voltage derived from the peak voltage and the bottom voltage. When receiving the stop signal, the peak voltage detection block stops the operation to detect the peak voltage and retains the peak voltage detected before the reception of the stop signal while the same signal is being received. When receiving the stop signal, the bottom voltage detection block stops the operation to detect the bottom voltage and retains the bottom voltage detected before the reception of the stop signal while the same signal is being received.
