Audio processor with head amplifier for VHS hi-fi TDA9605H
Notes
1. Amplitude modulated single carrier signal of 60 mV (RMS) on pin HMSW; for playback mode HPD = 1. Control
bandwidth is defined as the modulation frequency at which the amplitude modulation is attenuated with 3 dB by the
HF AGC.
2. Sample-and-hold audio distortion is measured using a HID control signal of 500 Hz on pin RMHID, f
mod
= 10 kHz and
∆f
FM
= 50 kHz. Audio distortion is measured using a 3 kHz 4th-order low-pass filter. The measured value is corrected
with 24 dB in order to calculate the equivalent distortion for the standard NTSC 29.97 Hz HID control signal.
3. B = 20 Hz to 20 kHz, unweighted.
