A DSP engineer applies DFT to 500 data samples that are sampled at 250 Hz to plot the signal spectrum. What is the frequency that corresponds to the frequency bin number ?
Two skaters are moving towards each other on an ice rink. One skater (m1=45 kg) has a speed of 8.3 m/s towards the right. The other skater (m2=73 kg) has a speed of 4.8 m/s to the left. The skaters collide and grab on to each other.
Design the control unit for the single cycle pipeline implementation You can use any software you like, e.g. VHDL or Verilog HDL.
A system, linear and time invariant is described by the following difference equation: 4y[n-2] + 2y[n-1] + y[n] = x[n] a) Determine if the system is stable. b) Find the system response to the unit step.
A radio receiver for the HF band covers the frequency range 2 MHz to 30 MHz. The first IF frequency is 3.0 MHz and the local oscillator is above the received signal frequency.
The continuous-time counterpart to the N-point discrete-time MA filter is the I-interval continuous-time MA filter given by the input/output relationship y(t)=(1/I)*Integral of x(lamda) delta lambda where the bounds are from t-I
Let the input to a singly-balanced mixer, f(t), be given by V0 Sin (2 pi fs t). The local oscillator input p(t) is a square wave, alternating between 0 and +1 volt. The freqency of the square wave is 10 MHz, while for the input, fs is 100 KHz.
A box contains 50 diodes of which 10 are known to be bad. If the first diode drawn from the box was good, what is the probability that a second diode drawn will be good
A carousel, starting from rest, is brought to a full rotational speed of one revolution per 5.00 seconds. The angular acceleration during the process is 0.300 rad/s2. The radius of the carousel is 6.00 m.
Make a user interface (using matlab) for amplitude modulation and demodulation without using the ammod and demmod function. The program should ask the user the 3 types of message signal (Square ,sinc,sinusoidal, triangle, sawtooth)
A common energy consumption for a family is about 1000 kW hr / month. How much power would that be on the average. (Hint: Notice that hour and month are both units of time so kW hr per month is really a power unit.
A piston-cylinder device initially contains 1 m of nitrogen gas at 400kpa and 27 c. A resistance heater is turned on inside the cylinder which passes 70 kj of electricity to the nitrogen gas.
a block (m=0.0433 kg) is sitting on a frictionless horizontal surface. The mass is connected to a spring with a spring constant of 24.5 N/m. The block is pulled back released from rest. The maximum acceleration of the block is 31.5 m/s^2.
