am tuner การใช้

Initially, AF117s were used in the AM tuner, but from serial number 13001, BF194 / 195s were adopted ( the FM sections used these silicon devices from the outset ).
That voice came from a Blaupunkt RNS 149 ( $ 1, 399, but available at about $ 999 ), combining an excellent FM-AM tuner and CD player with a navigation system.
They can resolve FM signals using slope detection, i . e . since FM signals also display AM properties at the boundaries of the bandwidth of the signal, you can " fudge " it by tuning an AM tuner to those boundaries.
Both the frequency response and the dynamic range of satellite channels can be superior to most, but not all AM or FM radio stations, as most AM and FM stations clip the audio peaks to sound louder; even the worst channels are still superior to most AM radios, but a very few AM tuners are equal to or better than the best FM or satellite broadcasts when tuned to a local station, even if not capable of stereo.
