Ratio Meter Circuit Diagrams
Many times, it is necessary to measure the ratio between two different frequencies, instead of measuring just the absolute value of a single frequency. The ratio meter featured here compares two frequencies, and displays the ratio between them. The higher frequency source is connected to SIGNAL IN 1 (f1) terminal, while the lower frequency source is connected to SIGNAL IN 2 (f2) terminal. The result is displayed digitally by LD1,LD2, and LD3. The measured ratio value that can be displayed is up to 99.9.

Ratio Meter Circuit
Many times, it is necessary to measure the ratio between two different frequencies, instead of measuring just the absolute value of a single frequency.
The ratio meter featured here compares two frequencies, and displays the ratio between them.
The higher frequency source is connected to SIGNAL IN 1 (f1) terminal, while the lower frequency source is connected to SIGNAL IN 2 (f2) terminal.
The result is displayed digitally by LD1,LD2, and LD3. The measured ratio value that can be displayed is up to 99.9.
The heart of the circuit is a MK50398 divider IC. The displayed value is exactly the quotient of f1/f2.
