Summary

This block multiplies both inputs by factor and outputs the result immediately after the multiply and outputs a delayed copy of the input by 1 cycle,

Mask Parameters

Parameter	Variable	Description
Factor	factor	The value that multiplies both inputs.
Mult latency	latency	The latency of the multiplier.

Ports

Port	Dir	Data Type	Description
a	IN	Inherited	The first number to be multiplied by factor. It usually is the real component of an input.
b	IN	Inherited	The second number to be multiplied by factor. It usually is the imaginary component of an input.
a_out	OUT	Inherited	The input a delayed by 1 cycle.
b_out	OUT	Inherited	The input b delayed by 1 cycle.
real	OUT	Inherited	The result of the multiplication of a with factor.
imag	OUT	Inherited	The result of the multiplication of b with factor.

Description

Usage

a_out and b_out are 1 cycle delayed versions of a and b, respectively. real and imag are the results of a * factor and b * factor, respectively. The delay from a to real or b to imag is equal to latency.
