#94054 - RMS Calculation |
Hi all,
RMS Calculation: How to calculate RMS value of signal ? Any language will do... Controller used: 89c668, 8051 instruction set 1) I can collect all the samples and then apply mathematical formula and calculate RMS value. 2) For that I need to find Square of each sample Cumulative addition of squared samples Divison/Mean Square Root Now I need help regarding square root calculation. Is it advisable to use 'sqrt' function supported by Keil? If not, which algorithm would be best for square root calc.? *** And another issue is abt clock speed How to select particular clock speed? I know abt baud rates conideration etc... But does it alwayz mean, higher the clock rate, better the performance ??? How CLK affects system performance? Please guide me regarding both issues. Thanking You. Neil. |
