Abstract: A waveform acquisition system that captures and digitizes a wideband electrical signal through a bank of front end filters, frequency down converters, and conventional digitizers (A/D converters). A software algorithm reconstructs the composite input signal and applies the necessary corrections to remove the effects of hardware impairments. This approach is possible because it uses a class of filters that exhibit the quality of perfect waveform reconstruction, allowing signals whose spectral components overlap multiple filter bands, to be faithfully reconstructed. A calibration generator switched into the input port serves as a reference for quantifying and removing hardware errors. The channelized analog-to-digital converter (ADC) effectively multiplies the bandwidth and sampling rate of the conventional digitizer performance in a single channel by the number of channels in the system.

Abstract: Staggered interleaved Nyquist regions associated with differing ADC clock rates (FCLK) avoids spectrum lost through disjoint guard bands at the end of or between adjacent Nyquist regions. The staggered interleaved Nyquist regions overlap by an amount at least as much as is consumed by the guard bands. Selectable anti-aliasing filters associated with each Nyquist region and its ADC clock rate are used to enforce the staggered Nyquist regions and their various guard bands. For example, and neglecting guard bands, an initial raw band of operation RB1 may be the First Nyquist region for a basic sampling frequency Fs. An adjacent raw band of operation RB2 that overlaps RB1 may be the Second Nyquist region for an alternate sampling frequency 2Fs/3. An adjacent raw band of operation RB3 that overlaps RB2 may be the Second Nyquist region for the basic sampling frequency Fs. These raw bands interleave and overlap: RB1:DCtoFs/21st Nyq. for FCLK = Fs RB2:(2/3)Fs −to2(2Fs/3)/2 =2nd Nyq. for FCLK = 2Fs/3 (1/2)(2/3Fs) = Fs/3 2Fs/3 RB3:Fs − (1/2)Fs = Fs/2to2(Fs/2) = Fs2nd Nyq. for FCLK = Fs In this example the smallest overlap is Fs/6. We then select widths for guard bands that do not exceed Fs/6. Additional ADC clock rates and anti-aliasing filters may be used to operate in still higher Nyquist regions.

Abstract: A signal processing method and apparatus reducing distortion using divided signals differing in only amplitude by weighting an input signal by first weights ki (i=1 to 4) to obtain divided signals, performing the same signal processing f(x) on the divided signals, weighting the signal processed divided signals by second weights l1 (i=1 to 4), and adding the divided signals Vout1 to Vout4 weighted by the second weights. The first weights are k1=t, k2=−t, k3=1, k4=−1, while the second weights are l1=−1, l2=1, l3=t3, l4=−t3. Here, t=b/a (where a and b are different positive integers).

Abstract: A method for improving bandwidth of an oscilloscope involves, in preferred embodiments, the use of frequency up-conversion and down-conversion techniques. In an illustrative embodiment the technique involves separating an input signal into a high frequency content and a low frequency content, down-converting the high frequency content in the analog domain so that it may be processed by the oscilloscope's analog front end, digitizing the low frequency content and the down-converted high frequency content, and forming a digital representation of the received analog signal from the digitized low frequency content and high frequency content.

Abstract: The present invention provides an adaptive, intelligent transform based Analog to Information Converter (AIC) for wideband signals by directly converting an analog signal to information (e.g., features, decisions). This direct conversion is achieved by (i) capturing most of the information of a wideband signal via hardware/software implemented mathematical transformations, (ii) effectively removing unwanted signals such as jammer and interfere from the input signal, and (iii) using novel algorithms for highly accurate decision making and feature extraction (e.g., high probability of detection with low probability of false alarm). The jump in the improvement over today's state-of-the-art is in terms of effective and optimum signal information extraction at high-speed.
