1. The voltage gain of an 11.2 kHz low-pass filter is -12 dB; what is its numeric gain?

2. Two amplifiers are cascaded, one with a voltage gain of 6.02 db and the other with a voltage gain of 12. If 10 mV is measured at the input of the second amplifier, what is the voltage at the input of the first amplifier?

3. A passive high-pass filter is built from a 18 k ohm resistor and a 12 nF capacitor. What is its cutoff frequency?

4. For the filter in question 3, what is its numeric gain at10x its cutoff frequency and at 0.1x its cutoff frequency?
