FIGURE 4 shows an amplifier circuit. Write a short report on the operation and performance of the circuit. In completing the report you should:
- Explain the operation of the circuit and in particular the role of resistors R1 and R2.
- Build the circuit in PSpice and use it to determine:
(i) the quiescent value of Vout
(ii) the voltage gain for a 100 mV, 1 kHz , input signal
- Sketch the small-signal equivalent circuit of the amplifier and use it to estimate the voltage gain. Compare your answer with that of (ii) above.
- Attempt to calculate the quiescent value of Vout. Compare your answer with that given by the PSpice model. Try to explain any discrepancies.
Calculate the span, offset, step size, resolution, and percentage resolution for an analog range of 0 to 5 volts for 8-bit digital conversion. For such a system calculate the analog output of a D/A with the following digital inputs: $15, $4D, $7E,..
What Is the Concept of Dual beam CRO?
Construction on Hoover Dam was started in 1931 and finished in 1935, and the dam was in service from 1936. When completed, it was both the world's largest electric power producing facility and the world's largest concrete structure.
A finite state machine has one input, X, and one output, Z. The output becomes 1 and remains 1 thereafter when, starting from reset, at least two 1s and one 0 have occurred as inputs, regardless of the order in which they appeared.
Compare and contrast transmit and receive diversity. Describe how each diversity type lead to an improvement in system performance.
Use Shannon's expansion theorem to implement the following function using a 2:1 MUX and other non-MUX gates you may need. LetZ be your select bit and manipulate the formula directly (i.e.don't use the graphical trick).
A ball of radius 1 meter centered at the origin has uniformly distributed over its volume a positive charge Q. a. In moving a positive test charge from the point (x, y, z)= (2, 2, 2) to the point (4, 4, 4), do you have to do work on the test charge..
a. Write a Verilog code for a 2 to 1 Mux using gate-level structural level description. The two data input is D0 and D1, control input is C and output is Q. b. Write a Verilog code for a 2 to 1 Mux using behavioral level description.
What is the value of RTH?
1. Determine Laplace transform of (2-2e^-4t)u(t) 2. Determine if x(t) = 9cos(2t)+4sin(pi t) is periodic; if periodic, calculate the period. 3. Compute the inverse Laplace transform of X(s)= (s+2)/(s^2+ 7s + 12).
phosgene ccl2o is a colorless insidious, highly toxic gas which has been used as a war gas and is sometimes used in the preparation of organic chemicals. draw the lewis structure for phosgene ( Cis the central atom)
