I want a variable frequency square wave signal generator with the following specs:
1. Voltage 0-5 pp
2. Frequency 0-1 MHz
3. Output probes to attach to an oscilloscope
4. LED screen to display frequency
5. Keypad to key in desired frequency in 1 kHz units
6. Powered by either a DC battery or a USB
7. Specify all components required including casing
You may use an IC or microcontroller.
Question:
Since this is a design project, how will I know that the circuit will work as expected?
