Design a 3-tap FIR lowpass filter with a cutoff frequency of 1,500 Hz and a sampling rate of 8,000 Hz using
a. rectangular window function
b. Hamming window function.
Determine the transfer function and difference equation of the designed FIR system, and compute and plot the magnitude frequency responsefor Ω=0, π/4, π/2, 3π/4, and π radians.
The toggle switch has been closed for two minutes. During the first 15 seconds after the closing of the toggle switch, pushbutton I2 was pressed four times. Describe what the status of the motor and the pilot light (PL) will be at the two minute m..
How many atoms are found inside a unit cell of a simple cubic, body-centered cubic, and faced-centered cubic crystal How far apart interms of lattice constant a are nearest neighbor atoms in each case, measured from center to center
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
A constant current source of 2 mA is placed across a fully discharged capacitor of 100 F. In the time period before the capacitor reaches breakdown voltage, what is the time rate of change of voltage across the capacitor in V/s
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
Consider an ideal op-amp in inverting amplifier configuration with feedback impedance Rf=7ohms and an input impedance consisting of a series RL: Ri=9ohms and Li=5H. Let h(t) be the impulse response of the overall amplifer.
The dielectric materials used in real capacitors are not perfect insulators. A resistance called a leakage resistance in parallel with the capacitance can model this imperfection. A 170-F capacitor is initially charged to 100 V
the energy stored in a 4H inductor is 150J and is increasing at 200J/s at t=4s 1. determine the current magnitude at t=4s 2. determine the current voltage at t=4s 3. does the current enter or leave the positive terminal of the inductor
A linear CW product detector local oscillator has a 500 Hz error while detecting an AM signal. What will the receiver's output sound like What if the receiver is listening to a DSB or SSB signal
A special external data signal (DATA_READY) is asserted whenever each of the bits for X are available. In addition, another special signal (ENCODE) is asserted during the transmission of the data X indicating whether 2X+3 or 3X+1 should be compute..
The following test data were obtained from testing a 48kVA, 4800/240-V, step down transformer: Open-circuit test Voltage (V) 240 Current (A) 2 Power (W) 120 Short-circuit test Voltage (V) 150 Current (A)10 Current
An absolute optical rotary encoder has five tracks. How many bits is the output, and what is the resolution in degrees per state (that is, degrees per LSB)
