The secondary and higher order spectra (i.e. second and higher harmonics) of a broadcasted AM stereophonic signal are minimized by limiting the amplitude of the audio signal, prior to modulation onto the carrier, within a predetermined portion of the audio frequency range. This is achieved by ...
The AM signals are received by an AM antenna and then up-converted using a fixed-clock to a frequency range nearer to the FM signal frequencies. The up-converted AM frequencies are then processed using the receive path circuitry. A multiplexer (MUX) allows for selection of the FM signals ...

HRD-767 is equipped to receive AM, FM, and AIR frequencies, ensuring you stay connected to a wide range of broadcasts. The radio's sensitivity is impressive, capturing signals with precision, whether it's the latest news on AM or the latest hits on FM. The device's storage capacity is...
AM is widely used for long-range radio broadcasts but is prone to noise. FM is common in music broadcasting due to its noise resistance, while PM is mostly used in digital systems for its efficient data handling. 7. What are some real-life applications of the difference between AM, FM,...
The FCC announced the auction of the remaining spectrum in 2015, known in the broadcast TV industry as the channel "repack", resulting in the reconfiguration of channel allotment. In April 2017, all channels 38 and above have been deleted, but channel 37 remains reserved for radio astronomy in...
