The Shure SM7 is a professional cardioid dynamic microphone, commonly used in broadcasting applications since 1973. Designed by Shure, it has been described as an "iconic" industry standard microphone for its focused, directional sound and its widespread adoption in radio, television and recording studios. In 2007–2008, the SM7B model became ...
To avoid the response masking important radar targets behind the beacon, racons only operate for part of the time. In the United Kingdom , a duty cycle of about 30% is used — usually 20 seconds in which the racon will respond to radar signals is followed by 40 seconds when it will not, or sometimes 9 seconds on and 21 seconds off (as in the ...
A full-range loudspeaker drive unit is defined as a driver which reproduces as much of the audible frequency range as possible, within the limitations imposed by the physical constraints of a specific design. The frequency range of these drivers is maximized through the use of a whizzer cone and other means. Most single driver systems, such as ...
The response of a VU meter (black line) compared to instantaneous input level (grey area) of a drum beat. Level is in dB and time is in seconds. The rise time, defined as the time it takes for the needle to reach 99% of the distance to 0 VU when the VU-meter is submitted to a signal that steps from 0 to a level that reads 0 VU, is 300 ms.
Frequency response requirements differ depending on the application. [6] In high fidelity audio, an amplifier requires a flat frequency response of at least 20–20,000 Hz, with a tolerance as tight as ±0.1 dB in the mid-range frequencies around 1000 Hz; however, in telephony, a frequency response of 400–4,000 Hz, with a tolerance of ±1 dB ...
IQ imbalance is a performance-limiting issue in the design of a class of radio receivers known as direct conversion receivers. [a] These translate the received radio frequency (RF, or pass-band) signal directly from the carrier frequency to baseband using a single mixing stage. [b]
A component having a 'flat' frequency response will not change the weighting (i.e., intensity) of signal content across the specified frequency range. The frequency range often specified for audio components is between 20 Hz to 20 kHz, which broadly reflects the human hearing range (the highest audible frequency for most people is less than 20 ...
The Shure MV7 is a cardioid dynamic microphone used for podcasting and home studio applications. The MV7 was developed in 2020 by Shure as a digital audio reworking of the classic SM7B professional broadcasting microphone. The MV7 was rated the best podcasting microphone by Rolling Stone in their 2021 Audio Awards. [1]
