LM1889n also supports reduced carrier modulation where slight overmodulation inverts the carrier phase.
- while the TV receiver suppresses the LSB there is no need to filter the transmitter, because for low power, we don't care about wasting 50%.
if you wanted to make a simple SSB filter for Channel 2 or 3 or below for Ch 4 , it might look like this.
- note that this has two bandpass to spread the bandwidth with deep skirts and one lower SB is a notch filter. But in reality for local use filtering when no high power broadcast is using this channel, EMI is no issue, but be aware.
