He now had a filter section to which he had doubly applied the m-derivation process resulting in filter sections which he called the mm'- type.
22.
When the landlines are long and the two channels arrive by substantially different routes it can require many filter sections to fully equalise the delay.
23.
The image method of filter design determines the properties of filter sections by calculating the properties they have in an infinite chain of such sections.
24.
Many other types of filter section are intrinsically unbalanced and have to be transformed into a balanced implementation in these applications which increases the component count.
25.
The new variant boasts an updated sound engine, new filter sections and a " True Voice Unison " mode which can support up to 4 oscillators simultaneously.
26.
The T and the ? in the suffix refer to the shape of the filter section that would be formed if two half sections were to be connected back-to-back.
27.
However, to much surprise of musicians and journalists, it lost the sequencer audio tracks, digital input and output, and the digital filter section was downgraded, thus limiting sample-based synthesis.
28.
Many early dispersive filters were built using lumped element all-pass filter sections ., but these proved hard to fabricate with any accuracy and it was difficult to achieve a satisfactory and repeatable performance.
29.
Some passive filters, consisting of only one or two filter sections, are given special names including the L-section, T-section and ?-section, which are unbalanced filters, and the C-section, H-section and box-section, which are balanced.
30.
In general, each section will be minimum loss at a different frequency band, hence the amplification in that band will be limited to the basic loss of just that one filter section, assuming insignificant overlap.
