Given a system with input x(t) and output y(t) is described by the differential equation:d3y(t)/dt3 + 7d2y(t)/dt2 + 12dy(t)/dt = dx(t)/dt + 4x(t)
a. Find the transfer function H(s) and the impulse response, h(t) where Y(s)=H(s)X(s)b. Find the response, yb(t) with the input xb(t)=e-tU(t) and y(0)=dy(0)/dt=0.
Three loads 3+4j are connected in delta to a 208-V, three phase line find line current, power factor, real power, reactive power and complex power
Derive a minimal state table for an FSM that act as four bit parity generator. For every four bits that are observed on the input w during four consecutive clock cycles, the FSM generates the parity bit p = 1
To understand dierent signal models To be able to model a discrete-time system and design simple signal processing algorithms.
A standard silicon NPN BJT is to be used as an amplifier. The emitter voltage is biased at 4 volts, the base is biased at 5 volts, and the collector is biased at 10 volts. Will this circuit perform as desired? Why or why not.
Describe the relationship between peak voltage, peak-to-peak voltage and rms voltage. Include in the discussion which values can be demonstrated with the laboratory test equipment.
