Input signal condition	Input level	80dBμ
	Frequency Deviation	±4.0 kHz
	Modulation Frequency	1.0 kHz
Demodulated 3dB Bandwidth	Input the above signal and sweep the carrier around 450 kHz, and find Out the maximum audio output frequency. Then sweep the carrier frequency again and find two frequencies, which are observed –3dB attenuation points from the maximum point. Higher frequency point is called (f1) and lower called (f2). (F1-450KHz) is defined as upper 3dB bandwidth and (450KHz-f2) defined as lower 3dB bandwidth.
Demodulate Output	Demodulated output shall be measured when carrier frequency is adjusted to 450KHz.
Demodulated Distortion Factor	Carrier frequency is adjusted to 450KHz.And distortion shall be measured with 1 kHz modulation frequency.
