Design a lowpass FIR filter with the following specifications using MATLAB:Number of filter taps = determined on your trialsSampling rate =8000 HzPassband: 0 - 1200 HzStopband 1500 - 4000 HzPassband ripple: 1 dBStopband attenuation: 40 dB
(a) Print the lowpass FIR filter coefficients and plot the frequency responses using MATLAB. Label and print your graph.
(b) Determine the ripples in both pass-, and stop bands. Identify them on your plots.
Suppose that the machining operation requires 1 kW, that the tool machine ihas 90 percent efficiency, and that the supply current is 14 A rms with a power factor of 0.8. Find the AC machine efficiency.
A certain inverting amplifier has a closed-loop gain of 25. The op-amp has a open-loop gain of 100,000. If another op-amp with an open loop gain of 200,000 is substituted in the configuration, find the new closed-loop gain.
An industrial load consumes 88 kW at a power factor of 0.707 lagging from a 480 Vrms line. The transmission line resistance (Rline) from the power company's transformer to the plant is 0.08 Ohms.
Implement the carry-out and sum functions for a 1-bit full adder using a 3-to-8 decoder block with active-low outputs and additional gates (what gate types should be used). Complete the truth table and draw the circuit diagram
An office building is billed based on the rate structure given in Table 5.3 (Energy charges is $0.0732/KWh and demand charge is $9 / mo-kw. As a money saving strategy, during the 21 days per month that the office is occupied
a) Draw the state diagram b) Draw the schematic for the logic to implement this circuit using Inverters, AND gates, OR gates and D flip flops. Use the reverse side and additional sheets if needed.
Graded-index separate confinement double heterostructure (GRIN-SCH) InGaAs/GaAs lasers with various cavity lengths were tested in the lab. The 100m wide oxide strip lasers consists of two pairs of 10nm In0.2Ga0.8As quantum-well (QW).
The standard method of representing negative numbers in the binary system is with 2's complement notation. Let's start by discussing why this is the case. What are the advantages and disadvantages of using this method to represent negative numbers
Determine the maximum and minimum values of the magnitude response. How many peaks occur in the magnitude response in the frequencyrange from zero to 2π What are the locations of the peak and dips
The particle moves through one-quarter of a circle in a time of 2.30E-3 s, at which time it leaves the field heading due south. All during the motion the particle moves perpendicular to the magnetic field. What is the magnitude of the magnetic for..
A binary data stream needs to be transmitted at 5 Mbit/s by means of binary signaling. To reduce ISI, a cosine roll-off pulse of roll-factor r = 0.25 will be used. Determine the minimum required bandwidth for this transmission
A 150MW alternator generates an open-circut line-t0-line voltage of 12kV at nomial DC excitiation. When the terminals are placed in short-circuit the resulting current per phase is 8000A. a) Calculate the approximate value of the synchronous reacta..
