1- design op amp circuit to produce output vout which is related to inputs v1, v2 and v3 by expression vout= -(3v1+5v2+8v3). assume max permitted resistor value= 200k. use only one op amp
2- Design op amp circuit to produce output vout which is related to inputs v1, v2 by expression vout= (4v1+6v2) assume max permitted resistor value=100K. use only one op amp
A current of 4 A flows through a wire forming a "loop" circle of radius r. If the magnetic field in the center of the "loop" is 10 A, what is the radius along the "loop": a) if the loop consists of a loop of wire, b) if the "loop" consists of 20 t..
A phase modulation is used to transmit the signal s(t) = 10cos(20*pi*t) + 5sin(10*pi*t). kp = 3 rad/volts and fc = 20MHz a) What is the instantaneous frequency of the signal b) Write down the expression of the transmitted signal.
Based on these equations, determine the maximum power point. This is the value of and T that result in maximum power. State the power and the (,T) values. Do not assume this happens at 0.5T. The best way to do this is to make an Excel spreadsheet.
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
Formulate the differential equation model for a motor having inductance L and rotational inertia J, and electrical resistance Rw and frictional resistance Rf, driving a frictional load, Rl.
Consider two Si samples; one is p-type doped to 1018/cm3 acceptor atoms and the other one n-type doped to 1015/cm3 donor atoms at room temperature (300K). a. Draw the band diagram associated with p-type and n-type semiconductors, noting the various..
A digital system has a clock generator that produces pulses at a frequency of 16 MHz. Design a circuit (draw the logic diagram) that provides a clock with a cycle time of 250 ns.
Determine the coefficients p, q, and the determinant (delta) of the system: y1'=y1 + 10y2 Y'2=7y1 - 8y2 Based on these values, what is the type and stability of the critical point
