 Jun 3 comment Why doesn't the motion of a car affect the frequency of radio stations? @DARU SRINIVAS One interesting point to consider would be the effects on higher-frequency radios, such as ones used for cellular telephony (Say 1.9 GHz/2.1 GHz LTE) or L-band Digital Audio Broadcast at around 1,4 GHz. Jun 3 comment Where does background noise go on a radio station? About the loudness, it seems to me from your description that you're using an FM radio. An AM or SSB radio tuned to a unused frequency, especially if the band being used is "closed", that is to say is suffering from unfavorable radio-wave propagation conditions, will actually produce very quiet static. Due to effects of FM demodulation, you get the effect of very loud static.

However, since in real-life circuits both voltages and currents are real numbers... I really don't want to sound like Wikipedia, but I think that this is a great place to say "citation needed".

Also don't assume that I don't know to accept and upvote. Oct 7 awarded Popular Question Apr 9 comment How is formula for converting pressure from mmHg to Pa derived? Thanks a lot! The 15 character limit and 15 second limit is idiotic.
