    Abstract: A method for estimating signal-to-noise ratio (SNR) using a method with low bias that is effective for both positive SNRs and small to negative SNRs. The method is based on an iterative solution for the maximum likelihood estimate of the amplitude from which the SNR can be computed. The method is applicable for various modulated systems, including BPSK, QPSK and MPSK.

    Abstract: A flip-flop circuit is disclosed. The flip-flop circuit includes a single-input inverter, a dual-input inverter, a single-input tri-state inverter, a dual-input tri-state inverter, and two single-event transient (SET) filters. The single-input tri-state inverter receives an input signal D. The dual-input tri-state inverter includes a first input, a second input and an output, wherein the first input receives output signals from the dual-input inverter and the second input receives output signals from the dual-input inverter via the first SET filter. The output of the dual-input tri-state inverter sends output signals to a first input of the dual-input inverter and a second input of the dual-input inverter via the second SET filter. The single-input inverter receives inputs from the dual-input inverter to provide an output signal Q for the flip-flop circuit.
