Abstract

PURPOSE:To obtain a chirp analyzer which can simply select the weight function, by weighting the output of each stage of shift register to which the chirp analyzer compressed signal is fed, for the addition. CONSTITUTION:The chirp analyzer compressing signal inputted from the terminal 7 is fed to a shift register 9 via an A/D converter 98. After weighting the output of each stage of the register 9 with the multipliers 10a... of the weighting coefficient device 10, when addition is made at the adder 11, the weighting value of the result of weighting coefficient is the generic equation of various weighting functions. Thus, when the weight coefficient of the coefficient device 10 is changed with an electric signal, the weight function in response to the object of usage is selected, allowing to constitute the chirp analyzer which can simply select the weight function.
