Consider the circuit in Figure.
(a) Determine R1 such that IREF = 0.20 mA.
(b) Determine the values of R5 and R6 such that the maximum currents in Q5 and Q6 are 0.12 mA.
(c) Consider A = B = 0. What is IQ? Using the results of part (a), find RC1 so that vO1 = -0.7 V.
(d) Consider A = B = -0.7 V. What is IQ? Using the results of part (a), find RC1 so that vO2 = -0.7 V.
A motor with an efficiency of 76% supplies 20 hp to a load.It's power factor is 0.6 (lagging). A voltage of 440 VAC (RMS), 60Hz is applied to the motor. a. What is the real power applied to the motor in Watts
Suppose we have a resistive load that varies from 5 kOhms to 10 kOhms. We connect this load to an amplifier, and we need the voltage across the load to vary by less than 1 percent with variations in the load resistance.
It is required to design an equivalent analog filter using a digital filter and other appropriate components. Thesampling frequency is fsamp= 20 kHz and the attenuation (α)specifications of the filter are as follows: α > 42 dB for 0 4000 Hz.
Determine(using the thevenin equivalent circuit) what size resistor should be placed betweent R4 and R5 to ensure that resistor receives the maximum power possible from the power source
A copper strip (Ec = 105 GPa) and an aluminum strip (Ea = 75 GPa) are bonded together to form the composite beam shown. Knowing that the beam is bent about a horizontal axis by a couple of moment M = 35 N.m,
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.
The current regulator can be assumed as ideal, which means that the transfer function of the current regulation loop is unity. At t = 0s, the direction of the rotor flux linkage coincides with that of the magnetic axis of "a" phase winding.
1. What parameter of the intelligence signal causes or determines the rate of carrier frequency deviation 2. If you are tuned to an FM station at a frequency of 100.1 MHz, show the bandwidth allocation for two adjacent stations.
Convert the decimal number 431 to binary in 2 ways:(a) convertdirectly to binary; (b) convent first to hexadecimal and then from hexadecimal to binary. which method is faster.
