A DUT output signal under test contains frequencies from DC to 44 kHz. The DUT output impedance is guaranteed to fall between 50 and 100 Ω (purely resistive). We wish to measure the signal using a digitizer having a distributed cable capacitance of 120 pF plus a lumped input capacitance of 5 pF. Can this signal node be measured directly, or will a buffer amplifier be needed on the DIB?
1.draw a relay construction diagram and briefly explain the operation of a relay.2.define the terms normally open and
Open the neutral line, that is, force IN = 0, and again find the voltages V1 and V2. What is your answer? Would your home be better protected by adding a breaker to the return line?
Determine the voltmeter reading four time constants after the switch is closed.- Find the time that must pass before iC drops to 3 µA.
Polarization in dielectrics. The space between two large parallel plates, separated a distance d = 0.1 mm is filled with a dielectric with relative permittivity of 4. The plates are connected to a 12 V battery.
A digital system has three registers AR, BR, PR. Three flip flops provide the control variables for the system: S is a flipflop that is set by an external Start signal to start theoperation, and F and R are two flip flops used in sequencing the mi..
An ECG has a scalar magnitude of 1 mV on lead II and a scalar magnitude of 0.5 mV on lead III. Calculate the scalar magnitude on lead I.
Find the energy stored in the capacitor and inductor of given problem.- Find the current I1 and the voltage V1 for the circuit of given figure.
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
Find the system transfer function of a causal LSI system whose impulse response is given byh[n] = (-0.5)^n-1 sin[0.5(n-2)]u[n-2] and express the result in positive powers of z. Hint: The transfer function is just the z-transform of impulse respon..
It is required to design a full-wave rectifier using a center tapped rectifier to provide an output voltage of 10 v. Find the required number of turns ration of the transformer. Assume that a conducting diode has a voltage drop of 0.7v. The ac lin..
