a) Explain what is meant by 'unconditional stability' in an op-amp.
b) Figure 2 gives the open-loop response of an uncompensated op-amp. Compensation is to be applied to the amplifier to make it unconditionally stable. Estimate the frequency at which the breakpoint of the compensated response must occur.
A source X produces symbols A, B, C, D, and E with probabilities 0.5, 0.25, 0.125, 0.0625 and 0.0625 (a) Find the information content of X. (b) Give a fixed length code for X. Compute its efficiency. (c) Derive a Huffman code for X
What is the difference between the saturation and active regions of a BJT. What determines which region the transistor is in.
A constant torque of 5Nm is applied to an unloaded motor at rest attime t = 0. The motor reaches a speed of 1800rpm in 4s. Assumingthe damping to be negligible, calculate the motor inertia.
a mealy sequential network has two inputs andone output. if the total number of outputs recieved is >=4 andat least three pairs of inputs have occured,then the output shouldbe 1 coincidence with the last input pair in the sequence.
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
A sequential circuit hast two inputs (w1 and w2) and one output (z). Its function is to compare the input sequences on the two inputs. If w1 = w2 during any four consecutive clock cycles, the circuit produces a z=1; otherwise, z=0.
question 1ai give three advantages of a three-phase system over a single-phase system.ii there are two basic
A rectangular patch has length 13 cm and width 0.8*13 cm and is supported by a dielectric substrate with relative permittivity 4. What is (approximately) the resonance frequency (in GHz) of the patch antenna
The source-free circuit depicted in Fig. 9.1 is constructed using a 10mH inductor, a 1mF cPcitor, and a 1.5k ohm resistor. a) Calculate alpha, omega-sub-delta, and omega-sub-zero. b) write the equation which describes the current i for t>0.
Determine what kind of filter (low pass, high pass, bandpass, or band stop) the circuit represents. Briefly justify your answer. Confirm by computing the Bode plot using MATLAB and paste the graph below.
