AGC Characteristic
With an RMS of
, a supply voltage of 5 V, and a tuner
characteristic of 50 dB/V, the loop gain is:
Equation 2.4
Leading to:
Equation 2.5
To code Ks, LSI Logic uses an approximation to the nearest power of two.
LSI Logic uses the AGC_GAIN[2:0] register, with the following
correspondence:
Equation 2.6
Because the AGC_GAIN can have only a limited number of values, the
same is true of Ks. Thus:
Equation 2.7
In our example, AGC_GAIN=4isthe most appropriate value, giving a
value of
