% function [ECGsignals_filtered] = f_filterECG(ECGsignal, samplerate, hp_frq, lp_frq)
%
% Inputs:
%       signal: ecg signal to be filtered
%       samplerate: sample frequency in Hz of the signal 
%       lp_frq: cutoff frequency of the lowpass filter 
%       hp_frq: cutoff frequency of the highpass filter 

%
% Outputs:
%       ECGsignals_filtered: filtered ecg signal.
%
%
% Example Usage:
%       ecg_filtered = f_filterECG(ecg, 500, 0.5, 150)
