The upper side frequency of an AM signal is 603 KHz. If the carrier frequency is 600 KHz, what is the intelligence frequency
Design a frequency divider cicuit that will produce the following three ouput signal frequencies: 1 MHz. 800 kHz, and 100 kHz. Use 74HC160 and 74HC161 counter chips and any necessary gates. The input frequency is 12 MHz.
gaussian white noise perfectly band-limited to 0-10mhz is passed through a perfectly rectangular filter of bandwidth 18
A certain circuit is constructed with four elements inparallel: a 4 ohm resistor, a 10 ohms resistor, 1 uF capacitator,and a 2mH inductor. (a) compute α. (b) compute ω0 (c) is the circuit underdamped, critically damped oroverdamped Explain
AC source Voltage in series with R1(4 ohm) and then R2(1 ohm). Vs=9sin(2t +13degrees) find the instantaneous power deliverd to R2 (1ohm) at t=0,t=1,t=2
(a) Draw a circuit diagram and (b) calculate the total energy stored in the two capacitors. (c) What potential difference would be required across the same two capacitors connected in parallel for the combination to store the same amount of energy..
A switch turns the voltage source on and off. Evaluate the voltages across each of the capacitors and determine whether the energy changes due to the switch being turned on or off.
Pick two functions, x1(t) = cos(w1t) and x2(t) = sin(w2t) where w1 and w2 are dierent frequencies (to make life easy you should probably select these frequencies such that their ratio is a rational number). By hand, solve for the Fourier Transform..
A material is found to have a tenth-thickness of 2.3 cm for 1.25-MeV gamma rays. (a) What is the linear attenuation coefficient for this material (b) What is the half-thickness (c) What is the mean-free-path length for 1.25 MeV photons
Calculate A - B for the pair of numbers, 1101011, 0101010 assuming a two's complement number system and that the numbers are stored in one byte of memory. The numbers are in un-complemented form.
c) Write the SOP boolean equations as obtained directly from the partial truth table above and sketch a logic circuit diagram for them. d) Reduce the above equations step-by-step into the simplest form that would use only NAND gates.
Consider a portable 20cm2 fuel cell operating at 0.75V, 0.6 A/cm2. Suppose the stoichiometry of the anode is 2.0 and that of the cathode is 2.3. The fuel cell is expected to run for 3 days before being recharged.
1- Describe the function of the program. DO NOT WRITE THE OPERATION OF EACH INSTRUCTION 2- Assuming that the branch instruction is executed (the branch is taken), comput the number of clock cycles required to execute the loop (DECA or BNE AGAIN)
