What is a positive edge detector?

The idea behind a positive edge detector is to delay the original signal by one clock cycle, take its inverse and perform a logical AND with the original signal. The module shown above is named pos_edge_det and has two inputs and one output. The design aims to detect the positive edge of input sig, and output pe.

What is a signal edge detector?

Signal edge detection is a technique widely used in embedded software, model based development and electronics. A signal edge is defined as the transition of the signal from a high state to a low state or vice-versa.

What is edge detection algorithm?

Edge detection is an image processing technique for finding the boundaries of objects within images. It works by detecting discontinuities in brightness. Edge detection is used for image segmentation and data extraction in areas such as image processing, computer vision, and machine vision.

What is rising edge and falling edge?

A rising edge (or positive edge) is the low-to-high transition. A falling edge (or negative edge) is the high-to-low transition.
