AM transmitters must satisfy some conditions to be employed for digital audio broadcasting. The goal of this work is to determine the relationship between inter-modulation products on the transmitter output and the envelope and phase signals delay in case of complex modulating signals. The envelope signal path bandwidth is also...
In the 1970s, use of mobile radio frequencies was expanding dramatically and existing antennas were becoming heavily overloaded. The engineering solution was to introduce multiple transmitter combiners onto a single antenna using band-pass filters. The use of a beer barrel in this context shows how existing structures can be adapted...
