Design a digital security system for a four-door sedan car. There are sensors on all doors, hood, gas cover, and the trunk. When the car is locked, an alarm will sound if somebody tries to force open the door, hood, gas cover, the trunk, or tries to push/move the car. When the car is unlocked, the user is allowed to open the doors, hood, gas cover, or the trunk and drive the car. A shock sensor detects any major vibrations or move. Shock sensor sends out ‘0' when a shock/vibration is sensed. All other sensors send out ‘1' when it is in the closed condition. That is, when the door is closed, the door sensor sends out ‘1' to the security system. When a ‘1' is sent to the alarm (buzzer), it alarms. The lock sends out a ‘1' when it is locked. Draw a block diagram of the security system. Express the security system as a Function ‘F'. Draw the gate-level circuit for the security system. Explain the process of building the gate-level circuit. Use only and, or, not gates. Clearly state the assumptions made, if any.
Each city has a starting population and annual growth rate. The smaller city has the larger growth rate (required). Show the comparative populations of each city year by year until the smaller city has grown larger than the bigger city.
A 75-kVA, 230-V/115-V, 60-Hz was tested with these results: Open-circuit test: 115 V, 16.3 A, 750 W; Short-circuit test: 9.5 V, 326 A, 1200 W a) Determine the voltage regulation at rated load, 0.8 power factor lagging.
A truncated cone has a height of 50cm. The circular faces on the top and bottom have radii of 20 mm and 1mm, respectively. If the material from which the solid cone is constructed has a conductivity sigma of 2 x 10^6 S/m.
A communications channel has a bandwidth of 2,000 Hz and a signal-to noise-ratio (SNR) of 20 dB. What is the maximum possible data rate

A successive approximation A/D converter with range of 0 to 5 volts and a resolution of 0.05 volts is specified. It will be clocked at 500 KHz. a. Determine the number of bits that must be specified for this converter. b. Determine the t..
A shunt regulator utilizes a zener diode whose voltage is 5.1V at a current of 50 ma and whose incremental resistance is 8 ohms. The diode is fed from a supply of 12 V nominal voltage through a 220 ohm resistor
Knowledge about Circuit Analysis, A 5.1K resistor is connected between the cathode of a 6.2V zener diode and a 12V power supply
Design a BCD-to-7-segment decoder/driver (code converter) by using two different VHDLs (two projects - one low elvel and one high level) You need to turn in vhdl codes, testbench codes, simulation waveforms
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
Multiple charges at different locations are said to be in equilibrium if the force acting on any one of them is identical in magnitude and direction to the force acting on any of the others. Suppose we have two negative charges
