Radio systems sometimes suffer from multipath distortioncaused by 2 (or more) propagation paths between transmitter andreceiver. Suppose a channel output related to the input is:y(t) =K1x(t-t01)+K2(t-t02),where x(t) is the input, y(t) the output, and t01 and t02 are the transmission delays (K1 andK2 are simple constnants)(a) Evaluate the transfer function of the channel and(b) Specify the transfer function of an analog filter that eiminates the multipath distortion that produces thischannel.
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
Design a simple BJT amplifier circuit for receiving the over-the-air HDTV signals. The circuit should have a voltage gain of 10-100, assuming your signal source (antenna) is connected to amp through a cable with an impedance of 75
Carlos runs with velocity v=(5.0 m/s, 25 degrees north of east) for 10 min. How far north of his starting position does Carlos finish
A certain transducer is modeled with a source Vs and series resistance Rs. The voltage at its terminals is measured with a DVM having internal resistance Ri = 100 Mega ohms and is found to be 12.5 mV; adding a 5 Mega Ohms resistance in parallel
a) Explain why no hole is generated by the electron excitation involving a donor impurity atom. (b) Explain why no free electron is generated by the electron excitation involving an acceptor impurity atom.
The pulse generator circuit accepts a 16 Hz pulse and converts the signal to a 1 Hz pulse, that is, a clock signal once every second. This signal is then used to drive a counter that controls how the lights are illuminated.
Design an amplifier capable of providing the specified gain over a frequency range of 20 Hz to 10Khz under the following conditions. Input source is 2700ohms resistive, and the output load impedance is 32ohms resistive.
Write an algebraic expression for S3, the forth sum bit of a binary adder, as a function of inputs x0, x1, x2, x3, y0, y1, y2, and y,3. Assume that c0=0, and do not attempt to "multiply out" or minimize the expression.
If R1 = 220 k Ohms , R2 = 56 k Ohms, Rc = 6.8 k Ohms, RE = 2.2 k Ohms, B= 180, rO = 50 k Ohms, C1 = C2 = 10 uF, CE = 100 uF, and Vcc = 20 V, determine the voltage gain AV.
Develop the pseudo-code below for a program that will retrieve 2 bytes (NUM1 and NUM2) from memory, determine which is closest to the numeric value 50, and indicate the result by setting a variable named "CLOSEST" to 1
An electric motor is monitored with an ammeter, voltmeter, and wattmeter, which indicate 5.2 A, 120 V, and 480 W, respectively.Assume 60 Hz. a) Draw a phaser diagram of the voltage and current,assuming the voltage at zero phase and lagging current.
Make a sketch of the band diagram for an n-type semiconductor and a p-type semiconductor doped with phosphorus and boron at 5*10^15/cm^3 respectively. Label all the features of your drawing, as well as the relative energy
