An ideal discrete-time lowpass filter with cutoff frequency ωc = 2π/5 was designed using impulse invariance from an ideal continuous-time lowpass filter with cutoff frequency Ωc = 2π(4000) rad/s. What was the value of T Is this value unique? If not, find another value of T consistent with the information given.
An a.c. voltage, V, comprises of a fundamental voltage of 100 V rms at a frequency of 120 Hz, a 3rd harmonic which is 20% of the fundamental, a 5th harmonic which is 10% of the fundamental and at a phase angle of 1.2
A 50 mV signal is applied to the base of a properly biased transistor with r =10-ohm and Rc=560-ohm. Determine the signal voltage at the collector.
What is the de Broglie wavelength of an electron at 150eV. what is the wavelength for electrons at 10keV, which istypical of electron microscopes. Comparing this to visiblel light,comment on the advantages of electron microscopes.
1. An operator prepares an 8-bit binary value with a dip switch. 2. A momentary contact switch (single-pole-single throw) connected to only one end of a cross-coupled NAND latch is activated. This sets the output of the latch to a logic one.
In Astable multivibrator (using OP-AMP) and Butterworth 2nd order filter(using OP-AMP)(both high pass & low pass filter), both positive and negative feedback are given. But in Astable mutivibrator positive feedback dominates
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.
Design it to give an output that is 1/3 of the supply voltage. Furthermore, neither the power ratings of the resistors nor the current rating of the supply are to be exceeded. The voltage output of the divider must not change by more than 1% when ..
Natural gas consists primarily of methane, CH4(g). Write a balanced chemical equation for the complete combustion of methane to produce CO2(g) as the only carbon-containing product.
a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost
Show transcribed image text Four signals m1(t). m2(t). m3(t). and m4(t) are bandlimited to 3.6 kHz. 1.2 kHz. 1.2 kHz, and 1.2 kHz, respectively. These signals are to be transmitted using TDM.
Hence or otherwise obtain the current ratio I1/I2 in terms of the circuit inductances.
1.Convert 5EDA into binary number. What makes base 16 (Hexadecimal) an attractive numbering systems for representing values in computers 2. What is 4365 - 3412 when these values represent unsigned 12-bit octal numbers
