It is also referred to as an equalizer, leader bar, or double tree. It consists of a bar pivoted at or near the centre, with force applied from one direction to the pivot and from the other direction to the tips. Several whippletrees may be used in series to distribute the force further, such as to simulate pressure over an area as when ...
For example, the RIAA pre-emphasis in the popular Neumann SAB 74B equalizer applies a second-order roll off at 49.9 kHz, implemented by a Butterworth (maximally flat) active filter, plus an additional pole at 482 kHz. [2] This cannot be compensated for by a simple zero even if it were necessary, and in any case, other amplifiers will differ.
In the graphic equalizer, the input signal is sent to a bank of filters. Each filter passes the portion of the signal present in its own frequency range or band . The amplitude passed by each filter is adjusted using a slide control to boost or cut frequency components passed by that filter.
A television equalizer consequently typically requires more filter sections than an audio equalizer. To keep this manageable, television equalizer sections were often combined into a single network using ladder topology to form a Cauer equalizer. The second issue is that phase equalization is essential for an analog television signal.

In other cases, a specialized vehicle dolly can be attached to a standard vehicle hitch; for example, some moving vehicle rental companies, such as U-Haul, will rent these dollies for one-way transport of cars (flat tow bar towing). [7] [8] Hitch tow trucks are mostly sized for cars and light-duty trucks.
One taut-line hitch is tied 15–30 cm from the aircraft and adjusted for tension, then a second taut-line hitch is tied 5–20 cm further from the aircraft and finished with a half-hitch. Wind-induced lift tends to pull the knot tighter, gust-induced oscillations tend to damp-out, and once the half hitch is undone, pushing the lower working ...
Quick couplers (also called quick hitches) are used with construction machines to allow the rapid change of working tools or buckets and attachments on the machine. They remove the need to use hammers to manually drive out and insert the mounting pins for attachments.
