Choose the best answer for what a DC blocking or coupling capacitor does, assume the capacitor value is chosen to be too small.
Blocks the DC and is relatively high impedance to the AC voltage. Blocks only the AC voltage going into the next stage Blocks the DC voltage going into the next stage, but lets the AC signal go through Has a variable voltage gain and blocks the DC level Works well with a BJT transistor only
i- A 3-element uniform linear array with inter-element spacing of λ/2 is operated as a broadside array ,find the directions of null radiation , find the direction and the relative level of the side lobe. ii- if the peak radiation is to rotate by 30..
Draw a logic diagram of simple logic that converts the control variables CA, CB, and CC as inputs to outputs that are the SELECT inputs for the multiplexers and LOAD signals for the registers.
Compare the Bandwidths of Two Inverting Amplifiers a) Use Signal Express to measure the 3 dB bandwidth for the inverting amplifier with a gain of -10 and for an inverting amplifier with a gain of -50. b) How does the bandwidth change with gain
the charge entering the positive terminal of an element is q(t) = -12e-2t mC. and the power delivered to the element is p(t) = 2.4e-3t W . what is the current , voltage and energy of the element in the time interval 0
The arrival rate of calls at a mobile switiching station is 1 per second. The probability of k calls in a T second interval is giving by poisson PMF with h=arivial rate x T. What is the probability that there will be more than 100 calls placed in ..
The transfer function of a circuit is given by H(s)= 2s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator.
A system initially consists of 3 lbm of a substance having specific internal energy u of 20 Btu/lbm, and 6 lbm of the same substance having an internal energy of 30 Btu/lbm. 150 Btu of energy is transferred as heat to this system
Determine the corner frequencies and the limiting horizontal asymptotes of a common-emitter circuit with an emitter by pass capacitor. Consider the circuit with the parameters Re=4kΩ,Rc=2kΩ,Rs=0.5kΩ,Ce=1μF,v+=5v,V- =-5v.
Two batteries with 1.8 voltage and 10.5 Ohm internal resistance each are connected in series. This battery pack is used to boot a small electric motor with 275 Ohm resistance. Find the power delivered to the motor.
An AM signal has an unmodulated carrier voltage VC = 10VP, a load resistance of RL = 10, and a modulation index of m = 1. Determine Write down the frequency components of the received AM signal.
The pumps exhibit a surging effect with a period of 2.2 sec. What is the minimum sampling rate to ensure quality data. How much time can be spent processing each station's data. Data acquisition hardware and software take 200µ sec for a channel.
You are driving your car, and the traffic light ahead turns red. You apply the brakes for 2.70 s, and the velocity of the car decreases to + 4.71 m/s. The car's deceleration has a magnitude of 3.41 m/s2 during this time. What is the car's displace..
