One of the ways to look at programming at the assembly-language level is to consider it as putting together code fragments that do various little jobs. (This is a little higher-level than just thinking of it as a sequence of machine instructions.) Write short, snappy little code fragments to perform the following tasks:(a) Add two 16-bit numbers, one in file registers 0 and 1, and the other in file registers 2 and 3. (Most significant byte in the second registerin each case.)(b) Write a loop (its body consisting, in this case, of only a NOP in-struction) which will execute exactly a number of times determined by the value of the working register, W. (So, if W contains 33, the NOP in the loop should be executed exactly 33 times.)(c) Load the address of a variable (defined in a CBLOCK statement as "foo") into FSR0.(d) shift left 1 bit a 32-bit value, implemented as 4 memory locations, the address of which is in FSR1.
A receiver has a sensitivity of 0.3 µV. The same receiver can handle a signal level of 75 mV without overloading. The receiver has a blocking dynamic range of 80 dB. If the desired signal has a level of 10 µV
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
a certain ideal voltage generator is characterized as v(t) = 40 sin 377 t . If this generator is measured with a DC voltmeter, the instrument reads 12 volts, what is the rms value of this voltage waveform
For a 128-PSK modulator with an input data rate equal to 56 Mbps and a carrier frequency of 100 MHz, determine (a) minimum required bandwidth and (b) baud rate.
Consider an InGaAs APD with excess noise x=0.7, M=10 where M is the multiplication factor. The unmultiplied dark current is 10 nA and bandwidth is 700 MHz. What is the avalanche photodiode noise current per square root of bandwidth
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstable filter.
Discuss how energy is stored in capacitors and inductors. Are the equations linear or non-linear How do you know? Discuss the concept of duality and why it applies to many fundament engineering concepts.
(1) How much power is dissipated by a 2.4 k resistor in series with a 12V power supply (2) Determine the result of dividing the squares of 12V by 3.3 k ohms.
Cradle to death is a typical lifecycle for any given application. The useful life of a particular application will vary based on advancements in a given discipline. It is critical to continuously seek and identify new ways to adapt technology.
write a script that will call: a function to prompt the user for an angle in degrees and call a function to calculate and return the angle in radians (note:pi radian =180) and call a function to print the result.
Design a filter for a biomedical instrument to eliminate DC (f = 0), 500 Hz tone, and its corresponding harmonics. The system sampling rate is 2,000 Hz. Place all the required poles at the origin to obtain a FIR filter.
Design a counter that will execute the numerical sequence 0, 2, 4, 6,repetitively. Unwanted states should be directed into wanted states that give the simplest logic functions. - Identify the number of required JK D-FLIP FLOP;
