An oscillographic method of measuring frequency deviation of frequency-modulated signals

- Summary
- Metrics

Abstract

The above investigations have shown that the proposed oscillographic method is suitable for measuring large deviations (over 100 kc) with modulation indexes exceeding 10 and carrier frequencies up to 7·109 cps; under these conditions the error of measurement is less than 1%. The equipment required for measurements by this method is simple and available in any radio laboratory.
