Design a variable frequency divider using AHDL. The frequency divider should divide the input frequency by one of four different factors. The divide-by-factor is controlled by two mode controls, as described by the following function table. The mode controls are used to change the modulus of the counter used for the frequency division. The output waveform will be high for two clock cycles starting at state zero.

Hint: Define buried combinational circuit nodes (in the VARIABLE section) that can define (in the Logic section with Boolean expressions) the four different conditions that can exist when the counter should be recycled. Compile and simulate your results. Submit both your AHDL and waveform file.

M1 M0 Divide by:
0 0 5
0 1 10
1 0 12
1 1 15

Activity 4: (Problem 15.6)

Design a mod-31 LFSR counter using AHDL. The counter should have two synchronous controls, an active-low reset (resetn), and an active-high count enable (enable). Compile and simulate your results. Submit both your AHDL and waveform file.

A. An office manager has four employees and nine reports to be done. In how many ways can the reports be assigned to the employees so that each employee has at least one report to do.
b. Find the number of ways to put eight different books in five boxes, if no box is allowed
to be empty.

The voltage divider network of Figure 2.37 (attached file) is expected to provide 5 V at the output. The resistors, however, may not be exactly the same; that is, their tolerances are such that the resistances may not be exactly 5 kΩ.
a) If the resistors have ± 10 percent tolerance, find the worst-case output voltages.

(a) A potential divider is to supply a voltage of 10 V, constant to better than 10%, into a load which can draw current up to a maximum of 50 mA. Design a potential divider for a 40 V battery (internal resistance 1 ohm) that would guarantee these conditions.
(b) Determine Thevenin's circuit for the circuit of (a)

The circuit shown in the attached figure was built in the laboratory and V0 was measured to be 6.25V. Verify this measurement using the voltage divider principle, whether measured result is consistent with the figure.

Consider the following circuit. As shown, lossy current source drives 1Kohm load by means of a voltage divider circuit. It is desired to have 5mA flow through the load. R1 and R2 can be assigned any value.
Part One: What is the smallest value that R2 can have?
Part Two: What is the largest value that R1 can have?
