The Poetry of Attachment?
On this point, at least, Darwin might have concurred. Debate continues as to the maximum life-span of requited passionate love: Whichever is the case, passion does seem to come with programmed obsolescence.
The truth was revealed by the fMRI scans: Such a neurophysiological pattern reflects a common shift from passion towards another kind of love that Fisher labels attachment: If it took a million words to establish a sexual relationship with you, your boyfriend was apparently willing to absorb those costs, just as his male ancestors were. But if it takes only twenty words a day to maintain exclusive sexual access to you, why should he bother uttering more?
His motivational system has evolved to deploy his courtship effort where it makes a difference to his reproductive success — mainly by focusing it where it improves his rate of sexual intercourse.
Men apparently did not evolve from male ancestors who squandered high levels of verbal courtship effort on already-established relationships. Yet Patricia Ball and Kerry McSweeney have argued that a significant change did occur within this sub-genre during the nineteenth century, as cultural and philosophical developments in Victorian Britain led a number of poets to write about long-term love relationships as they existed within specific social contexts.

Unlike passion, this kind of love can also take interruptions from the kids: But we should look more closely at Patmore before characterising him as that rare exception to the evolutionary rule: Felix may be writing from within a marriage in The Angel in the Housebut he is primarily writing about a courtship. Shortly before the children make their presence felt, the couple jointly conceive a plan for a true poem of marital love: But this is only a projection two pages from the end of the book.
Instead, he moved dramatically away from the prosaic mundanities of marriage in his final work, The Unknown Eroswhere the poet seems to have been reconverted to the courtly religion of love, offering straight the attitude he had mocked in The Angel in the House: True, such imagery is no longer deployed in the service of adulterous passion; instead, Patmore's late odes offer a vision of nuptial bliss: Patmore's late poem may be couched in Marian language, but it strongly conveys that pagan sense of existential halfness described by Aristophanes in the Symposium.
Nothing reflects his retreat from the ins and outs of wedded life more clearly than this; Patmore's vision of transcendent love appears to be born out of a Platonic distaste for the merely physical, dissipating consummations of earthly existence: I, while the shop-girl fitted on The sand-shoes, look'd where, down the bay, The sea glow'd with a shrouded sun. Her gentle step, to go or come, Gains her more merit than a martyrdom; And, if she dance, it doth such grace confer As opes the heaven of heavens to more than her, And makes a rival of her worshipper.
To die unknown for her were little cost! Selected Poemsp. Answers the iron to the magnet's breath; What do they feel But death! The clouds of summer kiss in flame and rain, And are not found again; But the heavens themselves eternal are with fire Of unapproach'd desire, By the aching heart of Love, which cannot rest, In blissfullest pathos so indeed possess'd.Frequency Response Descriptions for LTI Systems
Perhaps the poetry of attachment is more likely to be found in the celebrated records of loss and mourning collected in the first part of The Unknown Eros. This was the example that Thomas Hardy followed when writing his own widower's sequence in —13, yet the comparison reminds us that only certain aspects of the marital relationship echo in the poetic imagination. Patmore's loss does not bring back such intense memories, but the creative flames that it ignites draw less sustenance from recollections of the familiar presence of the loved one than from her tantalising absence; this love poetry does not mourn the passing of comfortable attachment so much as cry out — somewhat melodramatically in this case — impassioned lack: Again, like Hardy, loss has transformed the familiar woman into an absent erotic ideal: The agonising sensation of existential halfness, and the aspiration towards some kind of spiritual union, appears more intense and poetically stimulating to Patmore than mere conjugal relations could ever be; it is no coincidence that the most authentic experience of physical passion communicated in this sequence occurs within a dream: Keeping with standard DSP notation, impulse responses use lower case variables, while the corresponding frequency responses are upper case.
Since h[ ] is the common symbol for the impulse response, H[ ] is used for the frequency response. Systems are described in the time domain by convolution, that is: In the frequency domain, the input spectrum is multiplied by the frequency response, resulting in the output spectrum.
In other words, convolution in the time domain corresponds to multiplication in the frequency domain. Figure shows an example of using the DFT to convert a system's impulse response into its frequency response. Figure a is the impulse response of the system.
Looking at this curve isn't going to give you the slightest idea what the system does. Taking a 64 point DFT of this impulse response produces the frequency response of the system, shown in b. Now the function of this system becomes obvious, it passes frequencies between 0.
It is a band-pass filter. The phase of the frequency response could also be examined; however, it is more difficult to interpret and less interesting. It will be discussed in upcoming chapters. Figure b is very jagged due to the low number of samples defining the curve. This situation can be improved by padding the impulse response with zeros before taking the DFT.
For example, adding zeros to make the impulse response samples long, as shown in cresults in the higher resolution frequency response shown in d. How much resolution can you obtain in the frequency response? In other words, there is nothing limiting the frequency resolution except the length of the DFT. This leads to a very important concept. Even though the impulse response is a discrete signal, the corresponding frequency response is continuous.
If you make the DFT longer, the resolution improves, and you obtain a better idea of what the continuous curve looks like. Remember what the frequency response represents: Since the input signal can contain any frequency between 0 and 0.
