NU9N AM Transmitter Hi Fi Audio Modulation Processing

If the negative modulation peaks can be limited to under 100%, then the positive peaks could be above 100% without distortion! This can ONLY be achieved with asymmetrical modulation. Symmetrical modulation, like a pure sine wave, can …

Amplitude Modulation

On 100% positive audio peaks waveform, as seen on an oscilloscope, doubles in voltage. Doubling load voltage on audio peaks also doubles load current on audio peaks. This means any AM signal with symmetrical 100% modulation, when measured using …

150% Positive Peaks - The AM Forum - Index

Yet another argument against excessive positive peaks is the much greater risk of punching a hole in the insulation in expensive mod iron or damaging other components. For those who care, a 375 watt carrier exceeds 1500 watts PEP above +100% mod. It's more effective to maximize the carrier, reign in the peaks, and properly process the audio.

Positive Peaks / Asymmetrical Modulation

For example: the positive modulation peaks are 8 div. the carrier voltage is 2 div. In this example the positive modulation capability is 8-3=6/2=3*100=300%. When there is modulation, the carrier voltage rice to its normal value, that is the double value of the carrier voltage with out modulation.

Amplitude Modulation ("AM") - QSL.net

When an AM transmitter is 100% modulated by a pure sine wave, the PEP (Peak Envelope Power), is 4 times the un-modulated carrier power. This is because the Audio Voltage modulating the carrier doubles the RF voltage at the peak, since the load resistance is constant, the RF current doubles at the same instant as the RF voltage.
