The abandonment of thermic engines is a mandatory goal to reduce CO2 emissions. The automotive industry is getting ready and among the aspects that are being discussed, there is also radio listening. On electric cars, HF interference is generated primarily by the frequency converter, a device that controls the amount of power delivered by the electric motor by turning the voltage on and off thousands of times per second. This generates signals that fall in the medium wave broadcast band: electrical noises (such as distortion and crackling) similar to those emitted by smartphones, TVs, computers, vacuum cleaners and hair dryers. In addition, static electricity, which creates crackles, increases with the power of the motors. So much so that some manufacturers, such as BMW, Mini, Tesla and Volkswagen have eliminated the AM band on their current cars. Others, like General Motors, are studying the problem, but the solution isn’t around the corner. Xperi Corporation, a leading digital radio company, whose HD Radio standard (a patent it owns) is used both in the FM and AM band, claims that its transmission system is not afraid of interference. And it presented test results at NAB Broadcast Engineering and Information Technology, the annual conference of American broadcasters. According to Pooja Nair, an engineer at Xperi Corporation, a fully digital AM signal resists interference much better than an analogue one.
