Input: Read this: Due to the tree structure of the filter bank, pre-echo problems are made worse, as the combined impulse response of the two filter banks does not, and cannot, provide an optimum solution in time/frequency resolution. Additionally, the combining of the two filter banks' outputs creates aliasing problems that must be handled partially by the "aliasing compensation" stage; however, that creates excess energy to be coded in the frequency domain, thereby decreasing coding efficiency.[citation needed]
Question: Combining two filter banks' outputs creates what kind of problem?

Output: aliasing

QUES: The introduction of new or equivalent deities coincided with Rome's most significant aggressive and defensive military forays. In 206 BC the Sibylline books commended the introduction of cult to the aniconic Magna Mater (Great Mother) from Pessinus, installed on the Palatine in 191 BC. The mystery cult to Bacchus followed; it was suppressed as subversive and unruly by decree of the Senate in 186 BC. Greek deities were brought within the sacred pomerium: temples were dedicated to Juventas (Hebe) in 191 BC, Diana (Artemis) in 179 BC, Mars (Ares) in 138 BC), and to Bona Dea, equivalent to Fauna, the female counterpart of the rural Faunus, supplemented by the Greek goddess Damia. Further Greek influences on cult images and types represented the Roman Penates as forms of the Greek Dioscuri. The military-political adventurers of the Later Republic introduced the Phrygian goddess Ma (identified with Roman Bellona, the Egyptian mystery-goddess Isis and Persian Mithras.)

What cult appeared from Pessinus in 206 BC?

QUES: In any case, Alexander's toppling of the Achaemenid Empire, after his victories at the battles of the Granicus, Issus and Gaugamela, and his advance as far as modern-day Pakistan and Tajikistan, provided an important outlet for Greek culture, via the creation of colonies and trade routes along the way. While the Alexandrian empire did not survive its creator's death intact, the cultural implications of the spread of Hellenism across much of the Middle East and Asia were to prove long lived as Greek became the lingua franca, a position it retained even in Roman times. Many Greeks settled in Hellenistic cities like Alexandria, Antioch and Seleucia. Two thousand years later, there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers.
Are any relatives of the first people of the Grecian world still around ?

ANS: there are still communities in Pakistan and Afghanistan, like the Kalash, who claim to be descended from Greek settlers.

On 9 December 2010, The Sun published a front-page story claiming that terrorist group Al-Qaeda had threatened a terrorist attack on Granada Television in Manchester to disrupt the episode of the soap opera Coronation Street to be transmitted live that evening. The paper cited unnamed sources, claiming "cops are throwing a ring of steel around tonight's live episode of Coronation Street over fears it has been targeted by Al-Qaeda." Later that morning, however, Greater Manchester Police categorically denied having "been made aware of any threat from Al-Qaeda or any other proscribed organisation." The Sun published a small correction on 28 December, admitting "that while cast and crew were subject to full body searches, there was no specific threat from Al-Qaeda as we reported." The apology had been negotiated by the Press Complaints Commission. For the day following the 2011 Norway attacks The Sun produced an early edition blaming the massacre on al-Qaeda. Later the perpetrator was revealed to be Anders Behring Breivik, a Norwegian nationalist.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the television program that would have been affected by the attack?
Ah, so.. Coronation Street
