o communications, one form of modulation (putting information such as a voice signal onto a carrier radio signal) is amplitude modulate or AM. A baseband voice signal f(t) modulated onto a radio carrier at angular frequency wc of amplitude A gives a modulated waveform of the form : g (t )equals A cos (omega subscript c t )open square brackets 1 plus f (t )close square brackets If the Fourier Transform of f(t) is F(w), find the Fourier Transform of g(t).

Like a key in a lock, the shape of the. must bind with the. of the recieving neuron

If two parallel light rays hit a mirror, they will not be parallel to each other after they reflect.

An ideal otto cycle has a compression ratio of 8. at the beginning of the compression process, air is at 95 kpa and 27°c, and 750 kj/kg of heat is transferred to air during the constant-volume heat-addition process. assuming constant specific heats at room temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. (4390 kpa, 1730 k; 423 kj/kg; 56.4%; 534 kpa)
