1) List and discuss two different reasons for logic minimization. Under what circumstances would the simplest implementation not be desirable?
2) Explain three different algebraic methods that can be used to minimize equations. In your explanation write generalized equations to show how each method is used. Notice the requirement is to explain, don't just write them down.
3) Is !A OR !B the same as !(A OR B)? Why or why not?
4) Draw two different circuits that can implement a NAND function using inverters and AND gates.
A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..
a. Determine the current I(t) required to produce the B-field 2cos(wt)(T) in terms of other variables, for a sinusoidal field of 60 Hz, and N=100 turns. b. Now assume that you have the above B-field generated inside the solenoid.
Find the dimension of the window, as measured at the top of the oxide, after ideal isotropic etching (i.e. no overetch). Draw a cross section of the window opening with the resist still on.
If designing a computer configuration for use as a workstation for one specific application, what aspects of the software need to be considered as part of the design process?
A 5.6 mF capacitor has initial voltage of 18 V.The energy stored in the capacitor is used to light up a 0.1 kOhm lamp. How much will be the lamp's power 6.7 sec after the switch has been turned on
Three amplifiers with power gains of 15, 22, and 7 are cascaded. The input power is 120 µW. What is the output power of the final amplifier stage
Find an application note or data sheet that describes a piece of hardware or software that performs Manchester encoding and decoding. Describe the method used for signal encoding, decoding, and clock recovery.
a. A WLAN uses the 1-Mbps IEEE 802.11 infrared standard and the 16-PPM modulation scheme. Compute the period of transmission (time between bits). b. What is the average time between pulses (1 values) and the corresponding average rate of pulse tran..
A student project is required to be portable and hand held. It requires 6 V DC power at a current of 150 mA. The batteries for the power supply must last for a minimum of 7 hours of continuous operation.
Assuming that the current through and inductor is i l(t) = 10exp(-t/3). Find at what time this current dropped by 50percent of its initial value.
Calculate Is and the current I for V = 700 mV for a pn junction for which Na = 1017 / cm³, Nd = 1016 / cm³, A = 200 µm², ni = 1.5 x 10^10 / cm³, Lp = 5 µm, Ln = 10 µm, Dp = 10 cm² / s, and Dn = 18 cm² / s
An engineer decides to take 600 samples at sampling frequency 9000Hz. A Fast Fourier Transform (fft) program was applied to obtain the frequency spectrum of the signal. What is the frequency resolution,df, for the analysis
