Title: Generation circuit for saw tooth wave signal
Inventor: SUZUKI KEIJI
IPC: H04N9/31
Filed: 1985-12-25
Abstract: PURPOSE:To obtain a saw tooth wave signal having a regulated amplitude level regardless of a frequency by controlling the charging current of a charging capacitor corresponding to the frequency. CONSTITUTION:When a vertical synchronizing pulse PV is supplied to a terminal 31, a pulse P1 having a regulated pulse width (tau) can be obtained at the leading edge, for example, of the vertical synchronizing pulse PV from a monostable multivibrator 32. Also, since a transistor 45 is turned on during that period, a charged potential at a capacitor 44 is discharged through the paths of a resistor 46 and the transistor 45. After that, since the transistor 45 is turned off, the charging current flows from the output side of an operational amplifier 41 to the output side of an operational amplifier 37 through the capacitor 44 and a resistor 40, and the capacitor 44 is charged gradually. Consequently, a vertical saw tooth wave signal VSAW synchronized with the vertical synchronizing pulse PV is outputted to an output terminal 43. Therefore, the charging current for the charging capacitor 44 becomes a value in proportion to the frequency of the vertical synchronizing pulse PV, and the inclination of the vertical saw tooth wave signal VSAW becomes the value similarly in proportion to the frequency of the vertical synchronizing pulse PV.
