suppose that you have a balanced stereo signal in which the left and right channels have the same voltage amplitude 500 mVpp. This time, however, you want to be able to mix these two channels into a single inverted output while independently varying the gain of the two channels. Design and build an op amp circuit with potentiometers so that you can independently vary the gain of the left and right channels. Choose resistors so that the overall output of your circuit ranges between 0.4Vpp (when both channels are set to minimum gain) and 16Vpp (when both channels are set to maximum gain).
Maximum value of frequency deviation is fixed at 75 kHz for commercial broadcasting by radio. Modulation frequency W = 15 kHz, then find the transmission bandwidth of signal and deviation ratio.
How is the problem-solving process different when programming in assembly language versus programming in ladder logic?
Assume that a receiver has a first amplifier stage with a 5KW input resistance, a gain of 300, an input audio signal of 20 mV, and an operating temperature of 27oC. When the amplifier is operating with a bandwidth first of 10 MHz,
assume that the probability that a new car is chosen given that its a fiat and nissan are .75 and .6 respectively. also the probability that an arbitrarily chosen car is a ford and nissan are 0.2 and 0.4 respectively. now, what is the probability ..

An adiabatic piston cylinder contains 1 kg of R-134a. Initially the conditions inside the piston are 200 kPa and 0 degrees C. An electric heater inside the device runs with constant voltage of 110 V and a constant 0.1A of current for one hour
Derive the expression for TRANSFER FUNCTION and write the expression for magnitude and phase of H(f).
Finding rms current through Capacitor and Inductor, A circuit consists of a sine wave signal generator and a reactive component (L or C). The output of the generator is a sine wave with a peak amplitude of 8.8 volts at a frequency of 10.0 kHz.
A capacitor in an RC circuit with R = 5.00 ohm and C = 6.00 mF is being charged. What is the time required for the capacitor voltage to reach 86.5 percent of its steady-state value
Suppose that an inductor is formed by N turns of a conductive wire wound around a magnetic material. The magnetic material forms a circular cylinder of radius r = 10 cm, and height h = 5 cm. The inductance of the inductor turns of N is defined as:..
Write a control algoirthm for a temperature control loop for a heat echanger (steam to hot water) employing a temperature control valve, controller, and thermostat. In your algorithm include a step change and ramp change.
A museum has three rooms, each with a motion sensor (m0, m1, m2) that outputs 1 when motion is detected. At night, the only person in the museum is one security guard who walks from room to room.
