Block: FIR Tap (fir_tap)
Block Author: Aaron Parsons
Document Author: Ben Blackman
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.
