From a source with Pin = 2.4 mW, we want to get Pout = 60 mW at a distance l = 20 km from the source. α for the transmission line is given to be 2.3 dB/km. The available amplifiers have adjustable power gain, but are subject to two limitations: (i) the input signal power must be at least 1 µW to overcome internal noise, and (ii) the output signal power must not be greater than 1 W to avoid nonlinear distortion. Design an appropriate system.
Apply the rule-of-thumb dc design presented in this section for a silicon npn BJT with β = 70 when the operating Q point is defined by I CQ = 15 mA and I BQ = 0.3 mA, with a dc s
a 4 bit synchronous counter uses flip flops with propagation delay times of 15ns each. what will be the maximum possible time requires for change of state?
Why is the signal first attenuated and then amplified?
Trap is called as Non-Maskable interrupts, which is used in emergency condition.
