A signal travels a distance of 75 feet in the time it takes to complete one cycle. What is its frequency?
2. What is the gain of an amplifier with an output of 1.5V and an input of 30uV?
3. What is the overall gain or attenuation of the combination formed by cascading the circuits described in problems 1 and 2?
4. 3 amplifiers with gains 15, 22, and 7 are cascaded; the input voltage is 120uV. What are the overall gain and the output voltages of each stage?
5. Compute for the noise produced by the system with a 2kHz bandwidth operating at 27 degrees Celsius.
