Signal Operations

Blocks for performing the following types of operations on a signal. (Blocks are available in the Signal Operations library.):

Delaying

Integer Delay
Delay an input by an integer number of sample periods

Variable Fractional Delay
Delay an input by a time-varying fractional number of sample periods

Variable Integer Delay
Delay the input by a time-varying integer number of sample periods

Padding

Pad
Alter the input size by padding or truncating rows and/or columns

Zero Pad
Alter the input size by zero-padding or truncating rows and/or columns

Resampling

Downsample
Resample an input at a lower rate by deleting samples

Repeat
Resample an input at a higher rate by repeating values

Upsample
Resample an input at a higher rate by inserting zeros

Miscellaneous Operations

Convolution
Compute the convolution of two inputs

Interpolation
Interpolate values of real input samples

Unwrap
Unwrap the phase of a signal

Window Function
Compute a window, and/or apply a window to an input signal

Sample and Hold
Sample and hold an input signal
