(a) Find the matched-filter frequency response function H(f) for a perfectly rectangular (video) pulse of duration τ, andamplitude A. (Assume the pulse extends in time from -π/2 to+π/2).
(b) Sketch (roughly) its magnitude abs {H(f)} for positive frequencies.
(c) Sketch (roughly) the output of the videomatched filter. (This can probably be done much easier by"inspection" than calculation).
Design an 8-bit register with 2 control inputs s1 and s0, 8 data inputs I7..I0, and 8 data outputs Q7..Q0. s1s0=00 means maintain the present value, s1s0=01 means load, and s1s0=10 means clear. s1s0=11 means to swap
A SEMICONDUCTOR IN THERMAL EQUILIBRIUM, HAS A HOLE CONCENTRATION OF P0=1016 CM-3 AND AN INTRINSIC CONCENTRATION OF Ni =1010 CM-3. THE MINORITY CARRIER LIFE TIME IS 4*10-7s.
A 1.80kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195N/m and a 290g metal ball is in the tray. The spring is below the tray, so it can oscillate up-and-down.
The 16giga-byte (GB=2^30 bytes) flash memory chip for an MP3player is 11mm by 15mm by 1mm. This memory chip holds 20,000photos. a) How many photos fit into a cube whose sides are 1mm
A circuit contains two flip-flops connected to a voltagesource of +10 Volts, each flip-flop draws a current of 10 mA during its operation, if we neglect the power dissipation of the remaining circuit, then what will be the overall power dissipatio..
A 5-volt intelligence amplitude causes the frequency to change to ± 25 kHz. What will be the carrier frequency variation corresponding to an intelligence amplitude of 10 volts
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
Let x1[n] = {-2,1,-3,-5,6,8} with arrow under -2 and x2[n]={1,2,3,4} with arrow under 1. a) determine circular convolution of 7 between x1[n] and x2[n] b) verify (a) calculations by computing the DFTs and IDFT.
The project has been broken down into the following modules: Power supply, Processor and motherboard with RAM, I/O circuit board, CD-ROM drive, Floppy drive LCD display, Keypad, Enclosure and all mechanical parts, Final assembly.
The four alkaline battery cells store a total of 200watt-seconds of energy. If the cassette player is drawing a constant 10mA from the battery pack, how long will the cassette operate at normal power
assume filter is connected to a pure resistive load. The cutoff frequency is not to drop below 25krad/s. What is the smallest load resistor that can be connected across the output terminals of the filter.
A 200-ohm transmission line is to be matched to a computer terminal with XL = (50 - j25) ohm by inserting an appropriate reactance in parallel with the line. if f = 800MHz and er = 4, determine the location nearest to the load at which inserting
