Consider the analog signal: Xa(t) = 3cos(300t). Determine the minimum sampling avoid aliasing. If this signal is sampled at 300 Hz, what is the frequency of the signal reconstructed from the sampled data points? If this signal is sampled at 200 Hz, what is the frequency of the signal reconstructed from the sampled data points?

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

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
