3 results about "Sigma delta modulation" patented technology

There is provided an adversarial self-supervised learning method for a sigma delta modulation device. The device comprises a loop filter including an operational amplifier, and a circuit including a plurality of capacitors, a plurality of resistors, and a plurality of switches, which are connected to the operational amplifier; a quantization part quantizing and outputting a signal that is output from the loop filter; a feed-back converter converting a digital signal output from the quantization part into an analog signal; a memory configured to store one or more instructions; and a processor configured to control turn on or off of the plurality of switches, and adjust resistor values in an equivalent circuit of the loop filter in order to compensate a notch frequency reduced in the loop filter for satisfying a second-order transfer function.

The present invention encompasses methods and systems of transcoding frame-based video to frame free video is provided. The method comprises receiving a frame-based video stream, upconverting the received frame-based video stream to produce an upconverted frame-based video stream at a higher frame rate than the received frame-based video stream, and modulating the upconverted frame-based video stream using discrete time sigma delta modulation to produce a frame free video stream. In addition, complimentary methods and systems are disclosed for transcoding frame free video to frame-based video.
