What is SOS form in Matlab?
The sos function converts the input IIR filter numerator and denominator coefficients into SOS matrix and scale values, and assigns these values to the dsp. SOSFilter object.
What is a SOS filter?
The SOS-filter is a simple sequence of two shaped pulses designed to populate and to store singlet spin order in coupled spin systems. The SOS-filter can be introduced as a block of an arbitrary NMR pulse sequence when one needs to detect only the spins that have passed through a long-lived singlet state.
How does Imfilter work in Matlab?
The imfilter function computes the value of each output pixel using double-precision, floating-point arithmetic. If the result exceeds the range of the data type, then imfilter truncates the result to the allowed range of the data type. If it is an integer data type, then imfilter rounds fractional values.
