1 A common way to specify the performance of a radio receiver is to give its noise temperature The idea is to measure the actual noise power at the beginning of the receiver, and then assume that it comes from a resistor that is placed across the input Often, in fact, there is just such a resistor in that position The total white noise power obeys the law N kTKBm watts, which was given in Section 41 Suppose that the bandwidth Bm over which the power measurement takes place is 1 MHz Find the power that will be observed if the resistor is at room temperature (Note: By international agreement among radio engineers, this temperature is taken as 290 Kelvin; for the most accurate answer, you can take this value) 2.

A common microwave radio link is one that carries information over about 50 km at a frequency of 4 GHz Suppose the antennas at both ends are 1 m diameter parabolic dishes, and suppose the transmitter power is 1 W Use the dish formulas in Section 41 to estimate how much power arrives at the receiver (Assume that the only power losses are the usual inverse square law propagation losses) 3 Suppose the radio link in Problem 42 is used to carry 1 Mbit/s by QPSK modulation and the receiver is the one in Problem 41 The exact nature of the signal does not much matter here; what we really need is an estimate for the bandwidth of the signal that reaches the receiver A good one is the 1/T Rule in Section 4.

3, which in this case states that the signal will have bandwidth 1 MHz, the same as the bit rate (a) Find the ratio of the signal power to the noise power at the beginning of the receiver, that is, the SNR (Remember that the bandwidth at the receiver input should be limited to that of the signal itself) (b) Suppose that an SNR of about 13 dB is enough to give a good error rate Keep using the 1/T Rule to estimate bandwidth, and estimate the bit rate that this link can carry at an SNR of 13 dB..

Why might you want regexes Consider an information processing task where you are trying to retrieve documents characterized by particular words; you can add a lot of precision if you can specify constraints like the words must be contained in the same sentence (you could use a pattern specifying something like word1, any number of characters except full stop, word2 ) Or, as another example, imagine trying to find the targets of all the links in an HTML document You would need a pattern that specified something that could match an HTML link: <a href= .. and you would want the portion of the matched string starting at the point following the href= and going up to some terminating character.

<xsl:template match="p"> <fo:block xsl:use attribute sets="paragraph style"> <xsl:apply templates select="." mode="other attrs" /> <xsl:apply templates /> </fo:block> </xsl:template> <xsl:template match="p[@class = 'warning']" mode="other attrs"> <! attributes from the warning attribute set > </xsl:template>

(You would have to specify a clever pattern so as to get around little problems like the parentheses around the target name being optional, and the possibility of some arbitrary numbers of spaces occurring between <a and href tags) Perl represents the patterns as strings, usually delimited by the / character: /regular-expression/ You can use m<delimiter character> regular expression <delimiter character> if you don t want to use the default form for a pattern The =~ operator is used to effect a pattern match between the string value in a scalar and a regular expression pattern The result of a pattern match is a success or failure indicator; as a side effect, some variables defined in the Perl core will also be set to hold details of the part of the string that matched.

(There is also a don t match operator, !~ , which returns true if the string does not match the pattern) For the most part, regular expressions defined for Perl are similar to those that can be used with the Posix regular expression matching functions that are available in C programming libraries; however, Perl does have a few extensions..
