Measurement setup CD
Use Audio Signal disc SBC429 4822 397 30184
Measurement setup FM
Use bandpass filter to eliminate hum (50Hz, 100Hz) and
disturbance from pilottone (19kHz, 38kHz).
Measurement setup AM
To avoid admospheric interference all AM measurements
have to be carried out in a Farradays cage.
Use bandpass filter (or at least a high pass filter with 250Hz)
to eliminate hum (50Hz, 100Hz).
Bandpass
250Hz-15kHz
e.g. 7122 707 48001 LF Voltmeter e.g. PM2534 DUT
S/N and distortion meter e.g. Sound Technology ST1700B
