This block is a convenience wrapper around using a rotator block for frequency shifting. This block obfuscates the 2*Pi*freq/samp_rate phase_inc field and calculation, and only requires the designer to provide the frequency and sample rate.

Parameters

Sample Rate
Input Sample Rate

' Frequency Shift ' Amount of Frequency Shift to be applied to input signal (Hz)

Example Flowgraph

This flowgraph uses an Add Block to generate the classic "dial tone".
