4.Explain how to calculate the duty cycle of a pulse in terms of frequency and width.
5.Why is bit stuffing needed on a CAN system?
6. A communications channel has a bandwidth of 1,000 Hz and a signal-to-noise ratio (SNR) of 40 dB. What is the maximum possible data rate?
Suppose we want to construct an amplifier with a closed-loop gain of 50. We want the gain to vary by no more than +/- 5% while the open-loop gain varies by +/- 50%. Determine the values for a and b that will satisfy these constraints.
The maximum ratings for all resistors of this type are 250 (V) and ½ (W). What range of resistance values are limited by the maximum voltage rating of 250 (V), and what range of resistance values are limited by the maximum power of ½ (W)
how does the D'Arsonval movement work with voltmeter and ammeter i know how to design the cicuits but a little more of how the movement actually work in both cases. like for the ammeter the reason the resistor is place in parallel is to limit the ..
Suppose you are designing a power amplifier for a loudspeaker which has an equivalent resistance of 150 . What should be the Thevenin equivalent resistance of the power amplifier in order to maximize the power transfer to the loudspeaker
Use the simulation timing diagram to compare the worse case time to do an operation with your ALU with the worst case using the 74LS381. State which operation takes the longest and list the time required for both ALU's.
The capacitor in an RC circuit (R=10.0k Ohms and C=25.0uF) is initially uncharged. Determine the charge and current flowing in the circuit at 0.40 time constants (t=0.40 tau) after the circuit is connected to a 9.00 V battery.
Assuming that ideal filters are available, what is the lowest frequency at which the signal can be sampled and subsequently recovered in its analog form without distortion using a low pass filter?
The solution to Power Factor, Two single-phase loads are connected in parallel across a 415 V, 50 Hz supply. One load is rated 130 kW at a power factor of 0.75
Once a week a wagon driver leaves his hut and drives his wagon to the river dock to pick up supplies for his town. At 4:05 PM, one-fifth of the way to the dock, he passes the Temple. At 4:15 PM, one-third of the way, he passes the Preetam-Da-Dhaba..
Construct a table showing the current for values of time between 0 and 9 hours at intervals of 1 hour.Hence draw a graph of i against t for 0 is smaller or equal to t is smaller or equal 9.(cannot type in proper inequality symbols)
An LED is rated at VF=1.6V to 2.0V at IF=20mA. What value of series resistance is needed to limit the LED current to 20mA when this LED is connected to a 32 v peak source (that is, a source having a peak voltage of 32 v)
In each of the three phases in a balanced delta- connected load is composed of a 10mF capacitor in parellel with a series-connected 470 ohm resistor and 4mH inductor combination, assume a phase voltage of 400 V at 50 Hz
