Problem: 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]
What kind of structure does a filter bank have?
The answer is the following: tree

Problem: Restrictions on media censorship were significantly eased in August 2012 following demonstrations by hundreds of protesters who wore shirts demanding that the government "Stop Killing the Press." The most significant change has come in the form that media organisations will no longer have to submit their content to a censorship board before publication. However, as explained by one editorial in the exiled press The Irrawaddy, this new "freedom" has caused some Burmese journalists to simply see the new law as an attempt to create an environment of self-censorship as journalists "are required to follow 16 guidelines towards protecting the three national causes — non-disintegration of the Union, non-disintegration of national solidarity, perpetuation of sovereignty — and "journalistic ethics" to ensure their stories are accurate and do not jeopardise national security." In July 2014 five journalists were sentenced to 10 years in jail after publishing a report saying the country was planning to build a new chemical weapons plant. Journalists described the jailings as a blow to the recently-won news media freedoms that had followed five decades of censorship and persecution.

Problem: In September 1941, through the "Action Lauterbacher" plan, a ghettoisation of the remaining Hanoverian Jewish families began. Even before the Wannsee Conference, on 15 December 1941, the first Jews from Hanover were deported to Riga. A total of 2,400 people were deported, and very few survived. During the war seven concentration camps were constructed in Hanover, in which many Jews were confined. Of the approximately 4,800 Jews who had lived in Hannover in 1938, fewer than 100 were still in the city when troops of the United States Army arrived on 10 April 1945 to occupy Hanover at the end of the war.[citation needed] Today, a memorial at the Opera Square is a reminder of the persecution of the Jews in Hanover. After the war a large group of Orthodox Jewish survivors of the nearby Bergen-Belsen concentration camp settled in Hanover.
What plan was implemented in September 1941?
The answer is the following:
Action Lauterbacher
