derive a general formula for percent clipping of a unit amplitude sinusoidal test signal; this is the percent of time during one period in which the signal is clipped. The formula includes peak sinu
Wien Bridge Oscillator: Simulate the oscillator in Simulink with a gain block of 3.1 and a feedback transfer function of s/(1 + 3s + s2). Include a saturation element and limit the amplitude at 10v
The 9s complement of a BCD digit can be used similarly to the way ones and twos complements of binary numbers are used preform subtraction via addition. The 9s complement of a BCD digit is simply th
The counter must stop at a value which is defined by using the 8 slide switches. Use two seven segment displays to implement the counter, there must be 2 individual counting bits each per seven segm
Write a 4-bit up counter. Your counter has a asynchronous clear and when the clear is activated, the counter is reset to 3. The count range is from 3 to 9.
Design a mod-6 UP/DOWN counter: A) Using JK flip-flops and the state equation method. (Show the state diagram, state table, state equations, flip-flop input equations, and the logic diagram.)
Draw the state diagram for a sequence that detects the sequence 0101 using a minimal number of states. The detector should also detect overlapping sequences. Design the circuit using D flip-flops. D
Discuss some key characteristics of "load lines". What information does a load line provide you. Discuss key quantities from a zener diode data sheet. What are most important for a circuit designer.

A power amplifier has a gain of 15db and an input level of 2 volts. Assumming that the input and output impedance are the same. What is the voltage level at the amplifier output.
(1) Can we have Darlington transistor made up of an NPN and a PNP or do the two transistors have to be of the same type (2) Amplifiers has a power gain of 1,000 or 30dB. Where is that power coming fro
Using counters and state machines, use one slide switch to either read the switches that would set the duty cycle (count up to value) or cause the PWM to be running. If the slide switch is a &lsquo
The counter must stop at a value which is defined by using the 8 slide switches. Use the discrete LEDs as the output to validate the counter. The counter should run when a push button ‘run'
