Electronics and Communication Electromagnetic Field Theory Difficulty: Medium

For a common-base BJT configuration having I C = 5 mA and α = 0.97, an AC signal of 5 mV is applied between the base and emitter terminals. What is the value of output impedance and current gain? What is the name of 300 MHz of unlicensed spectrum allocated by FCC in ISM band? The value of Q in terms of conductance G and susceptance B of the circuit is define as: In an amplitude modulated system, if the total power is 600 W and the power in carrier is 400 W, then the modulation index is If z 0 is a zero of a (real-valued) linear-phase FIR filter then following is/are also zero/zeros of a (real-valued) linear-phase FIR filter,
