The signals are important thing in the nature because they carry some information that needed by the living thing. The most effective method to reduce noise level from the signals is filtering.
BackgroundSlide4
Which method that better for digital filtering corresponding to the components and output signal waveform?
Problem DefinitionSlide5
Lowpass Digital Filter
Infinite Impulse Response has the impulse response with infinite number of samples.
Theoretical Framework Slide6
The advantages of IIR digital filter :
Less delay time.Produce an equivalent magnitude response using a much lower filter order.Easier to design and lower cost to build.The IIR digital filter consist of two types:
Butterworth = no ripple in both
passband
and
stopband
Chebyshev
= has ripple in
passband
or
stopbandSlide7

ResultsSlide16
For this case, the suitable filter type and method based from the simulation is the Butterworth type filter and bilinear transformation method, because the filter type and method preferred give the output signal nearby similar to the required output signal.
Based from the required components to use, the Butterworth and Chebyshev filter with impulse invariance method use components at the least which only need two delays, one adder and three constant multipliers.
