1. Using block diagram reduction technique find closed loop transfer function of the system whose block diagram is shown in Fig. 1.
2. The signal flow graph for a feedback control system is shown in Fig. 2. Determine the closed loop transfer function C(s)/R(s).
3. The block diagram of a closed loop speed control of an armature controlled DC motor is shown in Fig.3. Convert the block diagram to a signal flow graph and determine transfer function using Mason's gain formula and given parameters.
Verify your result by using block diagram reduction techniques in MATLAB to obtain the overall transfer function between input and output.
A series resonant circuit has a resonant frequency of 10 kHz. The resistance of the circuit is 5 ohms and Xc at resonant is 200 ohms. a. find the bandwidth. b. find the cut-off frequencies. c. find Qs. d. if the input voltage is 30V
If an aircraft is present in a certain area,a radar correctly registers its presence with probability 0.99. If its is not present,the radar falsely registers an aircraft presence with probability 0.10. We assume that an aircraft is present with pr..
The heater element of an electric kettle has a constant resistance of 100 Ω ohm and the applied voltage is 250 V. Calculate the time taken to raise the temperature of one litre of water from 15°C to 90°C assuming that 85% of the power input
An input signal given by Vin(t)=5cos(500pi*t)+5cos(1000pi*t)+5cos(2000pi*t) is applied to a basic lowpass RC filter. R=318.3 ohms and C=1 microFarad. Find the expression for the output signal in terms of t and pi.
The binary-coded-decimal (BCD) format uses 4 bits to represent 10 decimal digits. For example, 259 in base 10 is repesented as "010 0101 101" in BCD format. A BCD incrementor adds 1 to a number in BCD format.
If R1 = 220 k Ohms , R2 = 56 k Ohms, Rc = 6.8 k Ohms, RE = 2.2 k Ohms, B= 180, rO = 50 k Ohms, C1 = C2 = 10 uF, CE = 100 uF, and Vcc = 20 V, determine the voltage gain AV.
A Si p-n-p transistor has impurity concentrations of 5´1018, 2´1017, and 1016 cm-3 in the emitter, base, and collector, respectively. The base width is 1.0mm, and the device cross-sectional area is 0.2 mm2.
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
a.) For a given tank circuit resonance frequency, what is the parameter that determines the bandwidth b.) What is the phase angle of a inductive susceptance
A 3-D printer lays down a semicircular arc of positively charged plastic with a radiusR = 3.5 cm, and a linear charge density of Lambda = +1.9 uC/m. After the printer has finished the arc, the stylus moves to the center of the arc.
