An electric resistance space heater is designed such that it resembles a rectangular box 55 cm high, 75 cm long, and 20
cm wide filled with 45 kg of oil. The heater is to be placed against a wall, and thus heat transfer from its back surface is
negligible. The surface temperature of the heater is not to exceed 75°C in a room at 25°C for safety considerations.
The emissivity of the outer surface of the heater is 0.8 and the average temperature of the ceiling and wall surfaces is the
same as the room air temperature.
The properties of air at 1 atm and the film temperature are: k = 0.02753 W/m-°C, v=1.798 x 10-5 m²/s, Pr = 0.7228, and ẞ=

Disregarding heat transfer from the bottom and top surfaces of the heater in anticipation that the top surface will be used as a shelf,
determine the power rating of the heater in W.
The power rating of the heater is
W.

Suppose you have 8 LED's connected to port-B (Bo-B7) of PIC16F877A and one switch
connected to port-D (Do) as shown in figure below. Write a program code that performs a
nibble (4-bits) toggling: if the switch is released then LED's (Bo to B3) are OFF and LED's
(B4 to B7) are ON, while if the switch is pressed then LED's (Bo to B3) are ON and LED's
(B4 to B7) are OFF. Use 300ms delay for each case with 4MHz frequency.

First, we note that R2 and C3 form a first order low pass filter and L3 and C4 form another low pass filter. Both low pass filters have been set at the same cutoff frequency. The combination of both form a two stage filter to remove the high frequency content present in the DAB signal. Capacitor C5 is used to remove any residual DC offset in the signal. But let's just deal with the AC steady state response, which means that you don't need to know any of these details, and then can conveniently treat this circuit as a blackbox.
