Abstract:
A signal power detection apparatus for detecting a power value of an inputted data signal, comprising:pulse generating means for generating a timing pulse having a phase that is sequentially shifted corresponding to the inputted data signal;power computing means for obtaining a voltage value of said inputted data signal in response to said timing pulse, and squaring the obtained voltage value to compute the power value of the inputted data signal; andaveraging means for averaging said computed power value of said inputted data signal,wherein said pulse generating means includesstoring means for storing a plurality of pulsed patterns differently shifted from each other in phase, wherefrom said pulsed patterns are sequentially read out in accordance with a reference clock signal,a frequency divider for frequency-dividing said reference clock signal, anda counter circuit for counting cyclically the frequency-divided clock signals outputted from said frequency divider up to the number of said pulsed patterns and producing a count number and said pulsed patterns are sequentially read out from said storing means in accordance with the count number counted by said counter circuit.
