Consider the sampling of real signal
a) Typically a speech signal that can be understood over a telephone shows frequencies from 100 to 5 Khz. What would be the sampling frequency fs(sample/sec) what would be used to sample speech without aliasing? How many samples would you need to save when storing an hour of spech? If each sample is presented by 8 bits, how many bits would you have too save for an hour of speech?
b) A music signal typpically displays frequencies from 1 up to 22 Khz. What would be the sampling frequency fs that would be used in a cd player?
c) If you have a signal that combines voice and musical instruments, what sampling frequency would yoou use to sample the signal? How would the signal sound if played at different frequency lower than the Nyquist sampling frequency?
Consider LTI system described by input-out relationship below y(t)=u(t) times integral(from minus infinity to t) (x(tau)) d(tau) a) Determine impulse response ,h(t), of the system without using Fourier and Laplace transform tools.
There is a 50 Mhz clock signal on the FPGA board. we want to have a 1 Hz signal for testing all the designs. Find out what size of the counter we need in order to obtain this signal from the on board clock.
Three loads 3+4j are connected in delta to a 208-V, three phase line find line current, power factor, real power, reactive power and complex power
Increasing the number of SIMD processors to 15 (assume this change doesn't affect any other performance metrics and that the code scales to the additional processors)
Assume that an oven has an electronic thermometer attached to circuitry with two outputs: one (H) is asserted when the temperature is above h, and the other (L) is asserted when the temperature is below l. Design a circuit that will turn the oven
What is the fundamental frequency of the spectrum of the square wave? What is the magnitude of the fundamental frequency component of the spectrum of the square wave?
a meter stick of uniform mass distribution and a mass of 0.150-kg is arranged as follows; a fulcrum is placed under the stick at the 20-cm mark on the stick. A mass of 0.100-kg is suspended from the 90-cm mark.
Design a signal conditioning circuit for a K-type thermocouple, which produces output voltage of 0V-5V using a three terminal solid-state temperature sensor for reference junction compensation. The sensitivity of the sensor is 4mV/C.
There are to be 15 states, and the device for utilization is a 22v10 chip using 8 flip flops internal to the device. The outputs are 8 LEDs and a secondary output Z that is a 1 if states 10,11,12,13 are active.
A transistor amplifier has a midband gain of -120, a high cutoff frequency of 36KHz, and a bandwidth of 35.8 KHz. In addition, the actual response is also about -15 dB at f=50Hz. Write the transfer function Av for the amplifier.
What is the difference between a D flip-flop and a J-K flip-flop How does the number of inputs affect the possible synchronous states of a flip-flop (Set, Reset, Hold, Toggle)
Consider a 4 channel CDM system with the following CHIPS: A: -1 -1 -1 1 B: -1 -1 1 -1 C: -1 1 -1 -1 D: -1 1 1 1 a) Show that each one of those chips is orthogonal to all of the others. b) If the CDM signal 1 -1 -3 1 is received, by all receivers, ..
