Adding a Constant

Modules:

add_const_cc()
add_const_ff()
add_const_ii()
add_const_sf()
add_const_ss()

for complex, floating point, integer, short+short->float and short.

Example usage:

	adjust = add_const_ff(25.25)

Instantiates a module to add a constant 25.25 to a signal.

Example:

	sampling_freq = 8e6
	fg = gr.flow_graph ()

	src0 = gr.sig_source_f (sampling_freq, gr.GR_SIN_WAVE, 396.15e3, 1, 10)

	normal = gr.add_const_ff(-10)
	dst_offset = gr.file_sink (gr.sizeof_float, "offset")
	dst_normal = gr.file_sink (gr.sizeof_float, "normal")

	fg.connect ( src0, dst_offset )
	fg.connect ( src0, normal )
	fg.connect ( normal, dst_normal )

This creates a signal of 396.15Khz with an ampitude of 1 and and offset of 10, and writes it to a disk file, "offset". It is also connected to a constant adder which adds -10 and then written to another disk file, "normal". The results, "offset":

and the file "normal":
