1. ECNG1006 – Digital Component
Design Project Helps
“The Frequency Meter”

2. Objectives of Project
This project investigates the digital design and implementation of a Frequency Meter using the Xilinx Schematic Editor

3. Complete System

4. Frequency Determination Unit

5. Changes Made
The ‘dataout’ of the modulo 4 counter is now 2 bits wide(00->01->10->11->00)
The ‘dataout’ of the modulo 4 counter is now connected to the ‘select’ of the 4x4bits multiplexer
LUT has to be re-done to match this change

6. Frequency Meter Display Unit

7. BCD to 7-Segment Converter

8. Design of circuit for Segment G

9. Design of circuit for Segment G

10. Design of circuit for Segment G

11. Implementation of circuit for Segment G

12. Changes were made to the following slides to match Display Unit Design changes made!!!!!!
