Build a 4-to-1 MUX using some tri-state buffers and two inverters(NOT gates). (Hint: you can build a 2-to-1 MUX using some tri-statebuffers and one inverter and then combine several 2-to-1 MUXes tobuild a 4-to-1 MUX.)
Write a program to determine how many from your data set called MYDATA, which is a set of unsigned single-byte numbers, are odd numbers. Save the result in TOTODD at address 0x10 in the data memory.
The sprinkler system is turned on ( set ON=1),if start = 1 The lawn is not fully watered and it is not raining. The output flow should be maximum when the lawn is too dry, medium when it is dry and drip when it is wet.
Design a digital notch filter to reject frequency 5 kHz completely and to have a sharp recovery on either side of 5 kHz to a gain of unity. The highest frequency to be processed is 20 kHz.
A transmitter transmits an AM sinal with a carrier frequncy of 1530kHz. When an inexpensive radio receiver (which has a poor selectivity in its RF-stage bandpass filter) is tuned to 1530kHz, the signal is heard loud and clear.
Typically, a speech signal that can be understood over a telephone shows frequencies from about 100 Hz to about 5 KHz. What would be the sampling frequency fs (samples/sec) that would be used to sample speech without aliasing.
Design a low pass active filter circuit such that its roll off attenuates frequency components at 10 kHz or more by more than 10 dB. Also, it is desired to have the passband gain positive that does not deviate from 20 dB by more then 3 dB.
A 35-year old female worker receives an x-ray exposure of 5.2 rad (whole-body) while carrying out emergency procedures in a nuclear accident. Discuss the health risks assumed by this worker as a result of the radiation exposure.
A firm leases land from you for 15 years to build a warehouse. As payment you will own the building after 15 years estimated to be worth $400k however you must pay taxes and maintenance of $15k per year.
A minimum solution requires six states. Design your circuit using NAND gates, NOR gates, and three D flip-flops. Any solution which is minimal for your state assignment and uses eight or fewer gates and inverters is acceptable. (Assign 000 to the ..
In a toaster the heating unit is a Nichrome wire whose resistance is 660 micro-ohm-CM/ft and resistance is 20 ohms.Determine the resistance of copper conductor of equalcross-section, but 10 times as long as the Nichrome wire.
Dtermine the resistancevalues for avoltage divider that must meet the following specifications. The currrent drain under the unload condition is nit to exceed 5mA. The soure voltage is to be 10V and 5V . Sketch the citcuit.
Discuss the various ways to include conditional program flow control in 80x86 assembly programming. What are some limitations implementing this flow control when compared to higher level languages
