Radio receiver testing method for car, involves storing digital signal in region of ultra-short wave-frequency band in main storage, and converting digital signal into analog signal, which is outputted to radio receiver after test drive

摘要

The method involves performing a test drive, and receiving an analog signal (a) at a connection of a vehicle antenna (1), where the analog signal is filtered using a filter (9) e.g. band-pass filter. The analog signal is converted into a digital signal (d). The digital signal in the region of an ultra-short wave-frequency band is stored in a main storage (21) i.e. double-data-rate three synchronous dynamic RAM. The stored digital signal is converted into another analog signal, which is outputted to a radio receiver of a vehicle after the test drive. An independent claim is also included for a device for receiving a radio signal.
