Design of Respiratory
Rate measurement SYSTEM using ECG through Recurrent NOTCH FILTER
Notch
filters are a highly discriminating, high-Q, method of the band stop filter
which can be used to discard a single or very small band of frequencies slightly
than a whole bandwidth of dissimilar frequencies. For example, it may be essential
to reject or reduce a specific frequency generating electrical noise (such as
mains hum) which has been prompted into a circuit from inductive loads such as
motors or ballast lighting, or the exclusion of harmonics, etc.
But
as well as clarifying, variable notch filters are also used by musicians in
sound apparatus such as graphic equalizers, synthesizers and electronic borders
to deal with narrow points in the sound response of the music. Then we can see
that notch filters are broadly used in much the same way as low-pass and
high-pass filters.
Notch
filters by design have a very slender and very deep stop band around their
center frequency with the width of the notch being labeled by its selectivity Q
in exactly the same way as resonance frequency peaks in RLC circuits.
Ultimately
most of the notch filter design is the twin-T notch filter network. In its
basic form, the twin-T, also called a parallel-tee, formation consists of two
RC branches in the form of two tee sections, that use three resistors and three
capacitors with opposite and opposing R and C elements in the tee part of its
design as shown, creating a deeper notch.
Notch
filters act as Band pass filters in which the obligatory ECG & PPG frequency
alone pass the filter initially. Regularity and amplitude is desirable to
filter the ECG & PPG signals.
To
measure the R Rate the system need to be picking up the peak values from the
given PPG & ECG Data sets. ECG
signals are very low level signals which contains mvolt of amplitude apart from
PQRST Peaks.The peaks also influence noise.
