Design a 4-bit combinational circuit 2’s complimenter. (The output generates 2’s
compliment of input binary number.) Show that the circuit can be constructed with XOR
gates.
Design a Combinational circuit using 2-input basic gates only which has three inputs A, B
& C and three outputs X, Y & Z. When the decimal equivalent of the binary input is 0, 1, 5
or 3, the decimal equivalent of the binary output is one greater than the input and when
decimal equivalent of the binary input is 4, 2, 6 or 7, the decimal equivalent of the binary
output is one less than the input.
What is the difference between ‘Ripple carry adder’ and ‘Look-ahead carry adder’ explain
in brief.
‘A 4-bit adder circuit could be used to convert BCD codes to Excess-3 codes’.
Justify this statement using proper circuit diagram in brief.
Find inverse Laplace transform of:
G(s)= S / (S+1) (S+1+j1)^2 (S+1-j1)^2
Solve step by step and briefly.
Line LM 58mm long is parallel to HP and inclined to VP at 45. If the point L is 20mm above HP and in VP then draw it's projections, also locate it's trace.
- A hydraulic cylinder has bore of 50 mm and moves a mass of 10 kg. It is controlled with a valve with a constant kv = 80 Pa/m. The damping coefficient is 2 Ns/m.
You are provided with the BC547 transistor and E24 series of resistors, along with a voltage supply of 10 V. If the transistor can be assumed to have a 𝛽 = 200, design a common-emitter amplifier to the following specifications:
a. The amplifier should be biased in the middle of the active region.
b. A sinusoidal output of amplitude 1 V should be obtained when a sinusoidal input of amplitude 10 mV and frequency 10 kHz, is applied from a source of resistance 5 kΩ.
A 1.00 M solution of Cu(NO3)2 is placed in a beaker with a strip of Cu metal. A 1.00 M solution
of SnSO4 is placed in a second beaker with a strip of Sn metal. A salt bridge connects the two
beakers, and wires to a voltmeter link the two metal electrodes.
a. What is being oxidized, and what is being reduced? Use table of reduction
A 50% total solids tomato puree is heated by steam as it flows through a steam injection heater (flash heating) at a rate of 500 kg/h. The steam (100% quality) is generated at 169.06 kPa and is flowing to the heater at a rate of 40 kg/h. The specific heat of the solids in the product is 3.2 kJ/kg K and the initial temperature of the puree is 40oC. Assume the specific heat of the solids in puree is not influenced by the heating process. Given: specific heat of water Cp = 4.18 kJ/kg K a. Draw a flow chart for the process with clear labeling. b. Make all necessary assumptions. c. Determine the temperature of the product leaving the heater. d. Determine the total solids content of the product after heating.
