Abstract: A PLL circuit for generating a modulated carrier signal includes a digitally controlled oscillator (DCO) to generate the modulated signal. The PLL circuit receives a desired phase change as a modulation signal at each cycle of a non-uniform clock, derived from the a DCO output and a uniform reference clock. This phase change adjusts the DCO's frequency. The circuit also receives a frequency control word, representing the ratio of the desired carrier frequency to the reference clock frequency. The phase change and frequency control word are accumulated to predict the DCO's output phase. A non-uniform clock compensation circuit calculates a compensation value for the phase change. A phase detector estimates the error between the predicted phase and the time offset between the reference clock and DCO output, generating a control signal for the DCO based on this error.

Abstract: Examples relate to a circuit arrangement, a time-mode arithmetic unit circuit arrangement, an all-digital phase-locked loop, and corresponding methods. A circuit arrangement is configured to discard charges from a capacitive circuit element of the circuit arrangement based on a width of one or more signal pulses of an input signal being provided to the circuit arrangement, with the rate at which the charges are discarded being dependent on at least one control signal being provided to the circuit arrangement. The circuit arrangement is configured to provide an output signal flank having a delay relative to a readout signal flank being provided to the circuit arrangement, with the delay being based on the charges stored in the capacitive circuit element at the time the readout signal flank is provided to the circuit arrangement.

Abstract: The invention relates to a method for changing the glucan chain lengths using fusion protein domains of various starch synthase enzymes in any starch or starch granule producing organism. The invention relates to identification of a GLucan ASSociation domain (herein after referred to as “GLASS” domain) of granule bound starch synthase (GBSS) used in combination with any other GLYcosyl TRransferase domain otherwise referred to as pfam00534-catalytic domain (herein after referred to as “GLYTR” domain) of one or more of any of the other starch synthase enzymes. The invention relates to identifying and using the new and surprising discovery that starch synthases are composed of at least two distinct functional domains herein after labeled as “GLASS” and “GLYTR”. More specifically, this invention relates to the genetic constructs that encode the fusions of the above domains and to the plants transformed with said constructs.

Abstract: A method of improving the CAS (customer premises equipment alert signal) tone signal detection of a telephone which uses a CAS tone signal detection chip or data signal processor in the telephone to detect a small segment of the CAS tone signal received from the exchange line and to trigger a CPU in producing an interruption signal, causing the telephone to mute the voice signal from the near end subscriber and to detect and judge the time series of the left CAS tone signal, and uses a voice signal detection circuit to monitor the voice signal from the far end subscriber, so that the telephone accurately measures the length of the CAS tone signal when no voice signal from the far end subscriber or the near end subscriber is detected, and judges, subject to the definition of a predetermined CAS tone signal length specification, whether the CAS tone signal is true or false.
