A computer employs RAM chips of 256 x 8and ROM chips of 1024 x 8. The computer system needs 2K bytes of RAM, 4K bytes of ROM, and four interface units, each with four registers. A memory-mapped I/0 configuration is used. The two highest-order bits of the address bus are assigned 00 for RAM, 01 for ROM, and 10 for interface registers.
a. How many RAM and ROM chips are needed?
b. Draw a memory-address map for the system.
c. Give the address range in hexadecimal for RAM, ROM, and interface.
1- Draw a circuit whose output goes to + V sat . When the input signal is below -4V. the output should be -V sat, when the input is above - 4V 2- Design a - 90 phase shift circuit at 1590 Hz , Then for your design calculate 0 at 15 Hz, & 15 KHz
Suppose you toss coins three times. Let X be the event that first of the three coin tosses results in "heads." Let Y be the event that you observe total of 2 "heads." Are X and Y independent events
A 100 W bulb takes 0.833A and a 200 W bulb takes 1.67 A from a 120V source. If the two bulb were connected across a 240 V source, what current in amperes will flow through the bulbs?
calculate the minimum sampling interval (time period for counting the pulse train) to achieve a speed resolution of 5 rpm, and the number of bits that must be there in the binary counter if the pulse train is to be sampled with this interval for a..
1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)
A silicon NPN bipolar junction transistor is to be used as an amplifier. What are the required bias conditions for this to occur If the emitter voltage is -3V, pick an acceptable base voltage and an acceptable collector voltage for the transistor ..
A set of digital scales is required to measure a load of 1000 N with an accuracy of ±1 N. Determine the minimum output resolution of the required ADC.
A lamp of 100 candela is placed 1 m below a plane mirror which reflects 90% of light falling on it. The lamp is hung 4 m above ground. Find the illumination.
Discuss the procedure for design using anthropometric data. Include Confidence Intervals (CIs). Select any one anthropometric measurement for males or females in Table 5.3 and find 90% CI for the mean measurement of the population.
Define Design with Multiplexer, Design a circuit using one 16 TO 1 multiplexer with W, X,Y,Z on the control inputs
Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 10Mbps using packets of length 1500bytes. Length of the ACK packet is also 1500 bytes.
Is there any advantage of star connection over delta w.r.t. induction motors? Also, is there any advantage or disadvantage of star connection over delta w.r.t. distribution and transmission of power? Please explain the reasons for all the advantag..
