circuit 2
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.

two switches connected to port-D (Do & D₁) as shown in figure below, according to the
following scenarios: (Hint: Use 500ms delay for each case with 4MHz frequency)
1. When Do=1 then B₁,B3,B, are ON.
2. When Do 0 then Bo,B2,B4, B5, B6 are ON.
3. When D₁=1 then B4,B,,B6,B7 are ON.
4. When D₁-0 then Bo,B1,B2,B3 are ON.

Square to sine waveform converter circuit How do we make sense of this? 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. What is the theoretical cutoff frequency for the RC and LC filters shown in Figure 9? Answer to within 1% accuracy. (a) RC Filter cutoff frequency (f 1) = kHzarrow_forward
