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.
Types of Field-Effect Transistors The channel of a FET (field-effect transistor) is doped to produce either an N-type semiconductor or a P-type semiconductor. The drain and so
explain appropriate first aid procedure to be followed in case of electric shock
Thermal noise This is the most significant noise in an ampli?er. It is produced by random movements of electrons in the resistors. This is caused by the ?uctuations in the volt
What are Difference Equations? A continuous-time system can be described by differential equations. Likewise, a discrete-time system can be explained by difference equations. T
