  • Digital to analog converter with improved companding
    Patent number: 3997892
    Abstract: A digital to analog converter includes nonlinear and linear cascaded resistive voltage dividers the nonlinear divider having its resistors valued to approximate a desired transfer characteristic. The high order bits of the digital input code select a predetermined resistor of the nonlinear divider and place the voltage across such resistor across the linear resistive divider the lower order bits of the code thereafter selecting a point on the linear divider which provides an analog value equivalent to the digital input code.

  • Reframing method for a carrier system having a serial digital data bit stream
    Patent number: 3940563
    Abstract: A reframing method for a T1 carrier type pulse code modulation digital data system utilizes the combination of the terminal frame code and the signalling code wherein four consecutive framing bits provide a unique four bit code indicating any one frame of a 12 frame. The method includes the steps of searching for the terminal frame code, synchronizing the framing code generator with the unique 4 bit code, and thereafter checking the three subsequent frames to insure proper reframing.
