I understand that deviation is affected by the voltage amplitude. Then modulation index is inversely proportional to the modulation frequency. In this case, the constant will be frequency deviation.
Hence Frequency deviation is not affected by the mixer.
Hence Frequency deviation is not affected by the mixer.
