文摘
- •
A quadratic polynomial power signal model is developed.
- •
A Fuzzy variable step size Linear combiner is used for frequency estimation.
- •
A Gauss–Newton ADALINE is used for the estimation of Amplitude and Phase.
- •
Damped sinusoids and decaying dc components are also tracked.
- •
Random variation of frequency is estimated accurately.
