A transmission line segment with Zo=50 Ohms and of length l is terminated at a load resistance of RL that can be varied. Sketch the input impedance Zin as a function of RL if l=(wavelength/4)?
An Ideal Low Pass Filter: The impulse response of an ideal low-pass filter is h(t) = sin(t)/t (or the sinc signal). (a) Given that the impulse response is the response of the system to an input x(t) = f(t)with zero initial conditions
A 10-bit unipolar ADC with a reference of 5.00 F and a 44 micro seconds conversion time will be used to collect data on time constant measurement. Thus, the input will be of the form V (t) = 4(1-e^t/T) . What is the minimum value of T
1. A potentiometer with a total range of 350° is supplied with a voltage of 12 Vdc. Find the output voltage for an angle of 135°. 2. An absolute optical rotary encoder has five tracks. How many bits is the output.
Design a circuit that given a 4-bit BCD digit(0-9) willproduce a 2-bit quotient and a 2-bit remainder for a division by3. This circuit will have four inputs the four bits of theBCD digit and four outputs 2 bits for the quotient and 2 bits forthe ..
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
Two teams of workers assemble automobile engines at a manufacturing plant in Michigan. Quality control personnel inspect a random sample of the teams assemblies and judge each assembly to be acceptable or unacceptable.
An incident wave of light travels through glass (n = 1.4) to water (n = 1.33) at an angle of 350. a. What is the angle of reflection and refraction b. What is the critical angle for this system
A design for high pass filter with butterworth characteristic is needed. Filter specification rewquire a cut-off frequency of 9 kHz for a sampling rate of 44 kHz, and a stop band attenuation of 40dB
Signal generator‘s internal impedance is purely resistive and has an open-circuit voltage of 3.5 V. When the generator is loaded with 22 ohms of resistance, its terminal voltage drops to 2.8 V. What is the generator's output impedance (pure resist..
Using the commonly available resistors, capacitors, and inductors, design a critically damped series RLC circuit (i.e., all three components are connected in series) with an undamped natural frequency of 20 krad/s.
PLC 2 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.
A linear-phase FIR filter should be designed with the ideal magnitude response shown in Figure 1 which represents an narrow band-pass filter. The lower cutoff frequency, fL , is 2,000 Hz, and higher cutoff frequency, fH , is 3,600 Hz.
