An analog signal consists of three sinusoids with frequencies 3.1 KHz, 4.82 KHz, and 5.64 KHz. The signal is sampled at asampling rate of 32 KHz producing the Discrete signal x(n).
Determine the normalized frequencies in x(n). [For this part i ended up getting F/Fs for the three frequnecies, ithink]
A signal x1(n) is produced by inserting a zero between samples of x(n). Determine the normalized frequencies in x1(n).
Find the heat energy generated by this amplifier. Assuming the BJT power transistor has a maximum junction temperature of 155 0C, if the ambient temperature is 25 0C, find the maximum allowable thermal resistance from the junction to ambient.
A stack controller is a digital circuit in a computer that implements last in firstout (LIFO) storage for temporary data. It operates analogously to a stack of plates where you can put a new plate on the top of the stack or you can take a plate of..
a) determine the wave equations for all three regions b) what is K for each region c) using matrix algebra, determine the coefficients to the wave eaquation in region 2
An absolute encoder is to be used for measurements that require a minimum resolution of 0.05 minute or arc. What is the number of bits required to achieve the specified resolution
Design four by four combinational binary multiplier using hierarchical design method, use switches as inputs, use LEDs as outputs, download design on FPGA and show your demo. You must design this part in VHDL.
What are the incremental savings that result from increasing the efficiency of a PV collector by 1% in terms of collector area and costs? Assume that the PV module represents about 50% of the total PV system cost.
three light bulbs (P1= 30W, P2=40W, P3=50W) are connected in series to a 120v source find the current i through the bulbs. Each bulb is rated 120 volts. how much power is each bulb absorbing do they generate much light
Assume that the inverters have a delay of 1 ns and the other gates have a delay of 2ns. Initially A = 0 and B = C = D = 1, and C changes to 0 at time = 2ns. Draw a timing diagram and identify the transient that occurs.
A pipe of inner radius 4 cm, outer radius 6 cm, and infinate length is centered on the z-axis. Charge is evenly distributed within the wall of the pipe in the amount of 16 coulombs per meter length.Find and Plot the electric feild density as a fun..
Telephone channels and PCM analysis, The analog to digital converter (ADC) used in a telephone system outputs 8 bit words. The digital words are transmitted as a serial stream to form a PCM voice signal
For an armature-control DC motor the following parameters are given: ea=22V, f=5x10^-3 onz-in/rad/sec, J=4.27X10^-4 in-onz-sec^2, La=0, Ts=10 onz-in (stall torque), wo= 480 rad/sec (no load speed), K=7.66 in-onz/amp.
How many kg of coal with energy content of 24 MJ/kg would be equivalent to energy used by a 100-W light bulb burning constantly for the whole year. Coal to electricity conversion efficiency is 30%.
