The voltage across the terminals of a certain circuit and the current entering into its (+) voltage terminal are given by:
v = 4 + 12 Cos[377 t + 60 Degree] - 6 Cos[754 t - 30 Degree]i = 5 + 10 Cos[377 t + 45 Degree] + 2 Cos[754 t + 15 Degree]
What is the average power?
Design a circuit with minimum number of gates for a binary multiplier that multiplies two unsigned four-bit numbers, Using Inverters, AND, OR gates and Full Adders.
discuss the difference(s) and similarity(ies) between the modulations index used in AM and the modulation index used in FM What are the practical interpretations
What is the resistivity of the wire? conductivity? Using the original dimensions of the wire, how much current can you pass through the wire until a 5V signal is degraded 5% or more?
To simulate a continuious-time system with input x(t) and impulse response h(t) using a digital system, one can first sample x(t) and h(t) to obtain x[n] and h[n] respectively and then perform a discrete-time convolution between x[n] and h[n]
Consider the Norton equivalent circuit with respect to terminals 'a' and 'b' for the circuit shown below. Suppose that Ro is given as 10 . The Norton equivalent current must be zero because there are no independent sources.
Determine the range of values of K such that the system is stable for s(s²+4s+10)+ k (s+5)=0
Digitizing an Audio Signal, PAM, ADC, An audio signal has a bandwidth that extends from 100 Hz to 10 kHz. The signal is sampled to create a PAM signal and then digitized by an analog to digital converter (ADC) that has 8 bits.
Design an interface for a ±24 V, 500 mA geared DC motor. The time constant of the motor is 10 ms. Include software to adjust the delivered power from 0 to 100%.
The shaft output of a three-phase, 60 Hz induction motor is 100 HP. The friction and windage losses are 900 W, the stator core loss is 4200 W, and the stator copper loss is 2700 W. If the slip is 3.75%, what is the effïciency of the motor
A calibrated RTD with alpha = 0. 0041 / degree C, R = 306. 5 ohm at 20 degree C, and PD = 30 mW / degree C will be used to measure a critical reaction temperature. Temperature must be measured between 50 degree and 100 degree C.
A baseband signal has frequency components from 5 kHz to 15 kHz. Determine (a) the theoretical minimum sampling rate and (b) the maximum time interval between successive samples.
A full-wave bridge rectifier circuit with a 1-kohms load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer having a single secondary winding
