On an ambiguity in the definition of the amplitude and phase of a signal
We point out that the conventional de"nition of instantaneous amplitude and frequency, namely as the magnitude and derivative of the phase, respectively, of a complex representation of the signal, sometimes contains an ambiguity, even for a unique complex representation (e.g., the analytic signal). There are at least two choices for resolving this ambiguity when it arises. One choice yields a n...
متن کاملDirection of arrival tracking below the ambiguity threshold
We present an algorithm for direction-of-arrival tracking that allows operation below the ambiguity threshold of the direction nding system. Using multiple target tracking techniques, the algorithm turns the most likely directions-of-arrival of each measurement into multiple potential tracks and then selects the true track as that with the maximum cumulative likelihood. The improvement o ered b...
متن کاملQuantization in the Presence of Large Amplitude Threshold Noise
Signal quantization in the presence of independent, identically distributed, large amplitude threshold noise is examined. It has previously been shown that when all quantization thresholds are set to the same value, this situation exhibits a form of stochastic resonance known as suprathreshold stochastic resonance. This means the optimal quantizer performance occurs for a small input signal-to-...
متن کاملNontrapping arrest of Langmuir wave damping near the threshold amplitude.
Evolution of a Langmuir wave is studied numerically for finite amplitudes slightly above the threshold which separates damping from nondamping cases. Arrest of linear damping is found to be a second-order effect due to ballistic evolution of perturbations, resonant power transfer between field and particles, and organization of phase space into a positive slope for the average distribution func...
