  • Compressed audio silencing
    Patent number: 4825303
    Abstract: A method and apparatus for suppressing spurious audio frequency sounds in a system in which electrically represented audio frequency sounds are very significantly raised in frequency and are conformed to a video line signal format. A sufficient number of guard samples ("M") are included at the beginning of each line of electrically represented audio frequency sounds to allow the amplitude response of the video line signal to reach the specified value prior to the occurrence of the samples that are used. The additional guard samples are provided by RAM memory (3), which is controlled by state machine (4). Fewer additional guard samples ("K") may be provided at the end of a video line to enhance tolerance to small timing variations.

  • Adaptive automatic gain control
    Patent number: 4625240
    Abstract: A method and apparatus for optimally processing television compressed audio signals by adaptively controlling the gain of the apparatus. The average value of the digitized signal is compared to a reference value to produce a gain control signal. A variable input video signal amplitude is automatically accommodated to a fixed analog to digital converter range.

  • Stepping motor signal circuit
    Patent number: 3974434
    Abstract: A plural phase stepping motor control circuit in which damping is accomplished by energizing a previously energized phase prior to the expiration of the power cycle on a pair of other phases. The duration of the damping pulse is inversely proportional to the speed of operation. The logic involved allows for forward or reverse running. A sprocket latch circuit locks out spurious overshoot responses, such as may be caused by vibration, damaged tape, or other irrationality.
