  • Solid state ringing switch
    Patent number: 4955053
    Abstract: A ringing switch for providing ringing voltage and tripping voltage to the cable pairs of a telephone central office. The switch synchronizes the control signal from a cadence generator with the zero crossing of the ringing voltage to ensure that the voltage at the switch output changes from the ringing voltage to the tripping voltage or vice versa only when the ringing voltage crosses the tripping voltage. Field effect transistors are used to switch the ringing voltage and a silicon controlled rectifier is used to switch the tripping voltage.

  • Circuit for generating two periodic signals having a controllable phase relationship therebetween
    Patent number: 4399410
    Abstract: A circuit for generating at least two periodic output signals having a phase relationship controllable between zero and 180 degrees as a function of a d.c. control signal as compared to a ramp signal. Also included is circuitry for controlling the phase relationship to be at substantially 180 degrees when the d.c. control signal is always greater than the ramp signal and to be at substantially zero degrees when the d.c. control signal is always less than the ramp signal.
