A charged particle (charge q, mass m) is moving under the influence of a magnetic field B = B0 az. If the velocity vector of the particle is v = v a ax +- vy ay + vx az Show that the acceleration of this particle lies in the x-y plane.
A class C amplifier severely distorts the signal. How can we use a resonant tuned filter to get the desired signal at the output What type of transistor (BJT or FET) would you like to use at the front end (first amplifier) of a receiver
(a) Design a high-pass filter with a cutoff frequency of 40 kHz. Use 0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency Give your answer both as ratio (Vout/Vin..
An AM receiver, operating with a sinusoidal modulating signal and 80 percent modulation, has an output signal-to-noise ratio of 30 dB. a) What is the correspoding carrier- to - noise ratio
In a motor control system, one master stop pushbutton (Stop) is available for stopping the operation at any time. If the temperature switch (TSW) is closed, pressing the red pushbutton (RedPB) will turn on both motors M1 and M2.
Assume the ASCII code is used for each character with an additional parity bit (in the most significant bit position, at left) Each character in ASCII is using 8 bits. a) What english word is coded by the following Hexadecimal sequence
If we wish to design a communication system which carries voice securely, we need to ensure that others cannot tap into the conversation. In digital transmissions, we can do this by encryption.
An ideal p-n junction diode has saturation current Is = 3e-15 A. Calculate the diode current.
State Carson's rule for bandwidth estimation. What does it reduce to for NBFM and WBFM and d erive an time domain expressionfor the output xd(t) of the system
The loop transfer function of a single-loop negative feedback system is: L(s) = Gc(s)G(s) = K(s + 2.5)(s + 3.2) / (s2(s + 1)(s + 10)(s + 30)) This system is called conditionally stable because it is stable only for a range of the gain K
A serial input finite state machine has one input and one output. The output becomes 1 and remains 1 thereafter when at least two 0's and at least two 1's have occurred as inputs, regardless of the order of occurrence. Draw a state diagram for the..
Find the applied voltage of an iron-core transformer if the secondary voltage is 240 v, and Np = 60 with Ns = 720
Half-Wave Rectifier, For the half-wave rectifier, the source is a sinusoid of 120 Vrms at a frequency of 60 Hz. The load resistor is 5 ohms. Determine
