A television signal generator includes a time constant circuit comprising a capacitor and resistors, and a control circuit for selecting resistance using the resistors. The generator generates a luminance signal having leading and trailing slopes at every leading and trailing edge of the signal in accordance with the angles of an outline of a desired pattern, shape and the like to the horizontal scanning lines of the signal, in response to the selection of resistance of the time constant circuit. |
