EMBEDDED SYSTEM Output Embedded Software PROGRAMMING Lowpass Filter

EMBEDDED SYSTEM 출력 (Output) 측정된 생체신호를 어떻게 처리할 것인가? Embedded Software

PROGRAMMING Low-pass Filter y(n) = {x(n)+2 x(n-1)+x(n-2)} /4 전의 값 저장 High-pass Filter y(n) = x(n) – 2 y(n-1) 전의 값 저장

PROGRAMMING f(t) n-1 n y(n) = x(n) – x(n-1)

PROGRAMMING HR 계산 Sampling frequency(fs) : 200 Hz Ts = 1/fs = 5 ms HR = {1000 / (r*5) } * 60
