  • Patent number: 8212699
    Abstract: Examples of a system and method for sigma-delta analog-to-digital conversion of an electrical input signal are disclosed. An electrical input signal is received. A filtered analog signal is provided based on the electrical input signal and an analog feedback signal. A digital representation of the filtered analog signal is provided, the digital representation being one of K quantization levels, wherein K is a positive integer between 2L and 2L+1, L being a positive integer. The analog feedback signal is obtained based on the digital representation.

  • Patent number: 8022854
    Abstract: Examples of systems and methods are provided for generating an output signal having an output code having less number of bits compared to an input signal having a thermometer code representation. The system may partition the input code bits into non-overlapping clusters. The system may generate a control signal for each of the clusters based on, at least in part, a logical OR operation over all bits in a corresponding one of the clusters. The system may determine a transition cluster comprising a 1/0 transition in the input code bits. The system may determine output code bits based on, at least in part, an input code bit pattern in the transition cluster and an identity of the transition cluster.

  • Patent number: 7973689
    Abstract: Examples of a system and method for sigma-delta analog-to-digital conversion of an electrical input signal are disclosed. A bandpass-filtered signal based on an electrical input signal and an analog feedback signal may be provided. A multi-bit digital representation of the bandpass-filtered signal may be provided. An analog representation of the multi-bit digital representation may be provided. A return-to-zero (RTZ) carving operation may be performed on the analog representation to obtain the analog feedback signal.

  • Patent number: 4471317
    Abstract: An AGC amplifier having a fast response for recovery and reacquisition of gain control in microseconds after a signal break including a first and second amplifiers interconnected by a delay line equalizer. An integrator control loop is responsive to the output of the second amplifier and is connected to the control means provided on the first amplifier and includes a feedback loop having a peak detector, an ideal integrator connected to the output of the peak detector and directly controlling the first amplifier using an ideal integrator capacitor loop during control operation and having a switch removable reset loop for operating as a fixed high gain amplifier in the absence of signal. The latter is determined by a comparator operating to receive a second peak detector signal not in the control loop.

  • Patent number: 4435734
    Abstract: High resolution video signals of bandwidth up to 25 mHz are recorded magnetically or optically, or are transmitted on a communications channel carrier with superior fidelity by using novel electronic circuit system including implementations of an FM modulator, writing amplifier, and wideband discriminator which enable coding and decoding with high accuracy, low noise, and low interference. The video signals are used to directly modulate a square wave carrier using an FM technique employing a very low center frequency-to-bandwidth ratio without need for subsequent frequency translations. A writing amplifier provides gain needed for saturated recording with unique provisions to balance transition amplitudes for minimum second harmonic distortion without affecting the primary phasing of transitions. A novel multiwinding inductor and pulse discriminator implementation is capable of demodulating the very wide deviation FM signal with good cancellation of the second harmonic and fundamental FM carrier spectrums.
