Which one of the following can be used for amplification of microwave signals? Let β be the short circuit common emitter current gain of a BJT biased in normal active mode. Let I C be the collector current is this β The input to a matched filter is given by \[s\left( t \right) = \left\{ {\begin{array}{*{20}{c}} {10\sin \left( {2\pi \times {{10}^6}} \right)}&{0 < t < {{10}^{ - 4}}\sec } \\ 0&{{\text{Otherwise}}} \end{array}} \right.\] The peak amplitude of the filter output is Gas flow and gas pressure can be measured by The information sent by paging system is known as a . . . . . . .
