Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz
why is the NPV of a relatively long- term project ( one in which its cash flow occurs in a distant future) more sensitive to changes in the WAAC than that of short term projects?
We have an amplifier with a 1 MHz bandwidth and a 20 mV input signal. The input noise = 1 mV, output signal 6.0 mV, and output noise = 1 mV. Find: (a) SNR at the input
Formulate the problem as a linear program (i.e. define the variables, and write down the objective function and all constraints in algebraic form).
