This patent describes an ignition timing control system for an internal combustion engine, comprising: a pulse generating circuit for generating first and second pulse signals corresponding to respective predetermined crank angles of the internal combustion engine; a rectangular wave generating circuit which receives the first and second pulse signals from the pulse generating circuit for generating a rectangular wave signal which rises at predetermined slope from an instant of generation of the first pulse signal, and which decays at slope less than the predetermined slope from an instant of generation of the second pulse signal; and a decision circuit which receives the rectangular wave signal.
