A load consisting of a 480 ohm resistor in parallel with a (5/9) uF capacitor is connected across the terminals of a sinusoidal voltage source, vg, where vg=240cos5000t V. a) What is the peak value of the instantaneous power delivered by the source
Design an active first-order RC low-pass filter (using a 741 op-amp) with a cut-off frequency of 10 kHz and a band-pass gain of 20 dB. Derive the step response and voltage transfer function.
An FM receiver is modulated with a signal having a baseband bandwidth of 15 kHz and the maximum frequency deviation is 45 kHz. Assume that preemphasis is added with a 3-dB boost frequency of 5 kHz.
The operational amplifier below has a specified input-bias current IIBup to 250nA and a maximal input-offset voltage VOS of ±3mV. It has a unity-gain frequency (gain-bandwidth product) of 1MHz.
Two loads connected in parallel are supplied from a single-phase 240-V rms source. The two loads draw a total real power of 400kw at a power factor 0f 0.8 lagging. One of the loads draws 120kW at a power factor of 0.96 leading. Find the complex po..
Draw a block diagram for a datapath that contains: an 8-word, three-port register file; an ALU that accepts operands either from the datapath or from an external source; and a shifter that shifts the A operand from the register file before it goes..
1. Give a summary of the article, what is the basic concept and the key technology. 2. What are the differences, advantages and disadvantages of the proposed technology compared to conventional MOSFETs and BJTs.
a) What is the minimum bandwidth that they need b) If the carrier amplitude in the transmitter (before the power amplifier at the output) is 5V, what is the maximum signal amplitude they can permit in the transmitter without introducing distortion
That is, the Irms value of an oscillating current is found by calculating the average power in the resistor and equating it to the direct-current power. Based upon this definition, calculate Irms for square-wave currents.
