<h1>AM demodulator plugin</h1>
<h2>Introduction</h2>
This plugin can be used to listen to a narrowband amplitude modulated signal. "Narrowband" means that the bandwidth can vary from 1 to 40 kHz.
<h2>Interface</h2>
![AM Demodulator plugin GUI](../../../doc/img/AMDemod_plugin.png)
<h3>1: Frequency shift from center frequency of reception</h3>
Use the wheels to adjust the frequency shift in Hz from the center frequency of reception. Left click on a digit sets the cursor position at this digit. Right click on a digit sets all digits on the right to zero. This effectively floors value at the digit position. Wheels are moved with the mousewheel while pointing at the wheel or by selecting the wheel with the left mouse click and using the keyboard arrows. Pressing shift simultaneously moves digit by 5 and pressing control moves it by 2.
<h3>2: PLL and synchronous AM</h2>
Use this toggle button to turn on or off the PLL locking and synchronous AM detection. When on the input signal is mixed with the NCO of the PLL that locks to the carrier of the AM transmission. Then the signal is processed as a DSB or SSB (see control 3) modulated signal. The main advantage compared to enveloppe detection is a better resilience to carrier selective fading. This does not prevents all selective fading distorsion but addresses the most annoying.
When the PLL is locked the icon lights up in green. The frequency shift from carrier appears in the tooltip. Locking indicator is pretty sharp with about +/- 100 Hz range.
<h3>3: DSB/SSB selection</h2>
Use the left mouse button to toggle DSB/SSB operation. Soemtimes one of the two sidebands is affected by interference. Selecting SSB may help by using only the sideband without interference. Right click to open a dialog to select which sideband is used (LSB or USB).
<h3>4: Channel power</h3>
Average total power in dB relative to a +/- 1.0 amplitude signal received in the pass band.
<h3>5: Audio mute and audio output select</h3>
Left click on this button to toggle audio mute for this channel. The button will light up in green if the squelch is open. This helps identifying which channels are active in a multi-channel configuration.
If you right click on it it will open a dialog to select the audio output device. See [audio management documentation](../../../sdrgui/audio.md) for details.
<h3>6: Level meter in dB</h3>
- top bar (green): average value
- bottom bar (blue green): instantaneous peak value
- tip vertical bar (bright green): peak hold value
<h3>7:Bandpass boxcar filter toggle</h3>
Use this button to enable or disable the bandpass boxcar (sharp) filter with low cutoff at 300 Hz and high cutoff at half the RF bandwidth. This may help readability of low signals on air traffic communications but degrades audio on comfortable AM broadcast transmissions.
<h3>8: RF bandwidth</h3>
This is the bandwidth in kHz of the channel signal before demodulation. It can be set continuously in 1 kHz steps from 1 to 40 kHz.
<h3>9: Volume</h3>
This is the volume of the audio signal from 0.0 (mute) to 10.0 (maximum). It can be varied continuously in 0.1 steps using the dial button.
<h3>10: Squelch threshold</h3>
This is the squelch threshold in dB. The average total power received in the signal bandwidth before demodulation is compared to this value and the squelch input is open above this value. It can be varied continuously in 0.1 dB steps from 0.0 to -100.0 dB using the dial button.
