Design a sequencer using D flip-flops that has two cycles. The even cycle sequences 0,2,4,6 and repeats. The odd cycle sequences 1,3,5,7 and repeats. An external input selects which cycle to perform. An input of 0selects the even cycle; an input of 1 selects the odd cycle. The cycles can be entered and exited only through states 0 and 1. Produce the following

(a) a state diagram
(b) a transition table
(c) k maps and reduce expression
(d) a logic diagram for the sequencer

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1
