Give the characteristic values of the input noise generators of an amplifier with amplification of 100 if, at grounded input, the output noise is characterized in the catalog as 5 microVolt/Hz0.5 ; and, with 100 kOhm generator resistance, the output noise is 500 microVolt/Hz0.5 , at the following extra condition:

1. Suppose that the input impedance is infinite.
2. Suppose that the input impedance is 100 kOhm.
