Assume that we will use a double-precision number for non-integer numbers (if you recall, this means a binary "scientific notation" with asign bit, 11 exponent bits using an excess-1024 representation, and a 53-bit mantissa of the form 1.--52 bits--.) What, precisely, is the largest number (decimal) we can represent? (This is half the "range.")
b)Assuming the same representation as the previous problem, how small would a number have to be in order for it to be indistinguishable from 0?
A transformer has a primary voltage of 115v and a secondary voltage of 24v. If the number of turns in the primary is 345, how many turns are in the secondary?
Characteristics of a filter, A filter has the following characteristics: Attenuation = 3.0 dB from 0 Hz to 2 kHz. From 2 kHz to 20 kHz attenuation increases from 3 dB to 23 dB in a straight line when plotted on axes of power in decibels (vertical a..
Determine the minimum signal to noise ratio (s/n) in dB required in each communication channel to achieve a data rate of 270 kbps?
calculate the minimum sampling interval (time period for counting the pulse train) to achieve a speed resolution of 5 rpm, and the number of bits that must be there in the binary counter if the pulse train is to be sampled with this interval for a..
Construction of different types of power transformer, significant energy savings
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
An electric pencil sharpener is rated 240 mW, 6 V is connected to a 9-V battery and a series-dropping resistor Rx needed to power the sharpener. Calculate the value of the series-dropping resistor Rx needed to power the sharpener.
generated by a loud speaker is reflected at two different walls with reflection coefficients r1 and r2. the signal x(t) recorded by amicrophone close to the loud speaker, after sampling is
Why can't a video signal such as an NTSC analog television signal be transmitted over a two km length of loaded twisted pair cable with a frequency range 300 Hz to 3,400 Hz? What is the bandwidth occupied by an NTSC video signal?
The open circuit voltage of the battery is 1.493 V. When a 100 resistor is connected across it, its measured voltage is 1.356V. Find its approximate Thevenin resistance and draw a model for the battery.
A positive charge of magnitude q1 lies at the origin. Derive an expression for the incremental work done in moving a second point charge q2 through a distance dx from the starting position (x, y, z) in the direction -ax.
Suppose station A and B are interconnected through two parallel unreliable links, where each link has a failure probability of 0.1. Calculate the average seconds per day when A and B lose communication.
