hi evry body:
iam a microcontroller beginner, and i stood AVR223:digital filter with AVR and AVR201:using the AVR hardware multiplier .
but now I don,t understand how can i singed numbers .
can anybody show me what is the mathematical algorithm (general algorithm) used to multipling
16-bit*16-bit=32-bit result where the numbers are signed.
pls another quistion :
how can i multipling the adc output (10-bit) by 16-bit
(signed multiplication).
the microcontroller used is atmega8.
