Title: Device for adjusting am radio receiver
Inventor: ISOKAWA MASAHITO
IPC: H04B1/16
Filed: 1990-11-28
Abstract: PURPOSE:To prevent mis-adjustment and retrial of adjustment by inputting an FM signal whose frequency swept to an AM radio receiver and adjusting components of the receiver receiving the signal such as a tuning circuit and an amplifier circuit automatically so as to bring the peak of a detection output to a prescribed position or to maximize the peak. CONSTITUTION:An FM signal generating circuit 2 generates an FM signal to an AM ratio receiver 1, and a sweeping circuit 3 generates a sweeping signal to sweep the frequency of the FM signal at a prescribed band. Thus, a detection output detecting means 4 detects the detection output of the receiver 1 and an adjusting means 5 adjusts the components of the receiver 1 in response to the detection output. Since the adjustment is implemented with a large input, mis-adjustment or retrial of adjustment is reduced.
