How does a transistor switch compare to a mechanical switch? In other words, a mechanical switch when it is ON has zero impedance. What about the transistor switch?
An FM transmitter delivers to a 75 ohm antenna a signal voltage of V (t)= 1000 sin (10^9t+4 sin 10^4t), determine: (a) carrier frequency; (b) intelligence frequency; (c)modulation index; and (d)total power in FM signal
A small magnetic needle, which is free to turn slowly in a horizontal plane, is placed at the center of the coil in question (6). Show that it will set at an angle \(\phi\) to B where \(cot(\phi) = 4R/(\pi n^2 \mu_{o}\omega a)\)
An alarm is powered by 120 VAC, and the on/off state of the alarm is controlled by an EM relay. Design the interface between a computer output port and the EM relay. The dropout voltage is 3.5 V, and the coil current needs at least 100 mA. Limit t..
Mrs. Brooke owns a robot with an FSM brain. The robot walks from left to right along a paper type containing a sequence of 1's and 0's. On each clock cycle, the robot walks to the next bit.
A 10kVA, 200/400V 50Hz single-phase transformer gave the following test results. O/C test: 200V, 1.3A, 120W, on l.v. side. S/C test: 22V, 30A, 200W on h.v. side. (a) Calculate the magnetizing current and the component corresponding to core loss at ..
Wavelength and Frequency, The downstream information (from the network to the customer) is transmitted at a wavelength of 1550 nanometers and the upstream information
A temperature sensor has a static transfer function of 0.15 mV/C° and a time constant of 3.3 s. If a step change of 22° to 50° C is applied at t=0, find the output voltage at 0.5 s from t=0s to t=10s
Design a circuit that will add either 1 or 2 to a 4-bit binary number N. Let the inputs N3, N2, N1, N0 represent N. The input K is a control signal. The circuit should have outputs M3, M2, M1, M0, which represent the 4-bit binary number M.
A FIR filter is depicted in the figure below. Assume that the system is at rest and an input sequence is applied to the system. Determine the first seven samples of the system output Assume that the system is initially at rest. x(n)=u(n)+u(n-1)-2u..
Find the applied voltage of an iron-core transformer if the secondary voltage is 240 v, and Np = 60 with Ns = 720
Design a 2-bit counter that, when f = 1, counts in the repeating sequence: 0, 2, 3, and when f = 0, counts in the reverse direction. Use T flip-flops. (a) Construct a state diagram or state table.
