What is the difference between power signal and energy
signal?
Answer Posted / aima khan
The power of a signal is the sum of the absolute squares of its time-domain samples divided by the signal length, or, equivalently, the square of its RMS level. The function bandpower allows you to calculate signal power in one step.
If we assume for definiteness a unit load (a 1 $Omega$ resistor), then if $f(t)$ is the voltage across the resistor or the current through the resistor, then the energy dissipated is
egin{displaymath}E_f = int_{-infty}^infty f^2(t) dt end{displaymath}
If this quantity is finite, then $f(t)$ is said to be an energy signal .

As a water tank loses heat, the temperature drops by 2 K/min when a heater is on, the system gains temperature at 4 K/min. A two-position controller has a 0.5 min control lag and a neutral zone of ± 4% of the setpoint about a setpoint of 323 K. Plot the heater temperature versus time. Find the oscillation period
