function rms = RMS(n, s, delta, K)

%%This function calculates the RMS at the points s where n is the sample number we start and s are the values of the signal

%%Calculate the rms
s_part = s(n-K:n-1).^2;                     %Get the part of s we need and square it
valuesum = sum(s_part);                     %Determine the sum
rms = sqrt(valuesum * (delta/K));           %Multiply our sum by delta on K and take the sqrt
