Variable Fractional Delay
5-495
Maximum delay
The maximum delay that the block can produce, D. Delay input values
exceeding this maximum are clipped at the maximum.
Interpolation filter half-length
Half the number of input samples to use in the FIR interpolation filter.
Interpolation points per input sample
The number of points per input sample, Q, at which a unique FIR
interpolation filter is computed.
Normalized input bandwidth
The bandwidth to which the interpolated output samples should be
constrained. A value of
1 specifies half the sample frequency.
Initial conditions
The values with which the block’s memory is initialized. See the Variable
Integer Delay block for more information.
