| Abstract: | Impulse and doublet functions are important functions in theories of signal analysis.They simplify the process of the signal analysis.Firstly,the definition of impulse function based on the distribution function and the physical meaning of the sampling property and sifting property of the impulse function are studied.Secondly,a doublet definition explainition based on the distribution function is presented for better understanding the physical meaning of doublet compared to the traditional definition,then t... |
