A non-sinusoidal voltage has a Fourier Series : V(t) = 10 + 30 Cos(2π60t+300) + 20 Cos(4π60t-600) + 25Cos(2π60t-200)+10 Cos(4π60t-300) This voltage is connected to a load which is 10? resistor and 20mH inductor connected in series. Find: i) The RMS voltage ii) The average voltage across the inductor iii) Find the current i(t) iv) Find the real power in second harmonic v) The total real power absorbed by the load
Given a parallel RC circuit with input voltage Vs, resistance value of R, capacitance value of C, and Vo taken across the capacitor. For this circuit, Vo/Vs=1/(jwRC+1), so the gain is 1 V/V. Is there any way to modify this circuit to make the gain..
discharge a capacitor of 1mF charged with a voltage of 1 volt we connect it, at time t = 0, with a esistor of R ohm. When we measure the voltage we find it to be V(r) (t) = e ^(-t) u(t). Determine the resistance of R. If the capacitor has a capaci..
A DC motor has the following parameters: Number of armature conductors = 60, length of rotor = 30 cm, radius of rotor = 10 cm, field flux density = 1 T, armature resistance = 1.2-ohm. Neglect the armature inductance. The maximum armature current r..
Suppose a signal from a vibrating motor is to be sampled discretelywith a digital data acquisition system to determine the RPM of the motor. It is known that the maximum possible RPM is 1800.
Assume an analog (1st Generation) dual mode mobile phone that is designed to operate in both the 900 MHz and 1900 MHz band which has been allocated for cellular networks. The mobile phone is using a superheterodyne receiver with a 500 MHz IF for b..
Use Matlab to verify the above results and determine: a. The starting torque b. The maximum torque c. The slip at which the motor develops maximum torque d. Draw the torque-speed characteristic of the motor
The mass spectrometer measurement section is a region of uniform magnetic field B= ˆxBms for z > 0. Ions enter the magnetic field (which exists for z > 0) at the origin with a known velocity +ˆz vz.
Find the signal-interference ratio in dB when 120-sectoring antenna is used and the propagation coefficient n =3. If a cluster is replicated 10 times within the system, find the total number of users that can be served with this wireless cellular sy..
design a negative edge-triggered d flip-flop that uses three sr latches constructed with cross-coupled nor gates.
a motorcycle battery delivers around 10 Volts DC, at an ampacity of about 500 Amps. this voltage goes through ignition (transformer) and it delivers about 30 KV to each spark plug. What is the turn ratio (Ns/Np) and the resulting ampacity on secon..
Assuming a 24 dB link margin is needed to account for fading and loss due to heavy rainfall on the longest link, while 12 dB link margin is sufficient for the shorter link, what transmitter powers are needed at each of the four transmitters
A USB communication link requires a circuit that produces the sequence 00000001. You are to design a synchronous sequential circuit that recognizes this sequence. Additionally, there is an E input to this circuit.
