The audio spectrum is the audible frequency range at which humans can hear and spans from 20 Hz to 20,000 Hz. The audio spectrum range spans from 20 Hz to 20,000 Hz and can be effectively broken down into seven different frequency bands , with each band having a different impact on the total sound.25 Nis 2020
Read moreWhat is the range of frequency in sound command?
Since the audible sound frequency ranges from 20Hz to 20kHz , a typical sampling rate for ADC is 48kHz or 44.1kHz, and the filter’s cut-off frequency is usually set about 20kHz .
Read moreWhat frequencies make up the mid band?
Mid-band typically refers to frequencies between 1 and 6 GHz .

Read moreWhat is HF frequency used for?
The band is used by international shortwave broadcasting stations (2.310 – 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services , among other uses.
Read moreWhy do we use higher frequency?
Increasing the frequencies will give everyone more “room” to transmit radiowaves . Increasing data rates, because having a higher carrier frequency also allows to widen the communication channel. Miniaturization (higher frequencies = lower wavelengths = smaller antennas and systems)
Read moreWhat is low frequency used for?
The Low Frequency (LF) band is mostly used for AM broadcasting in Europe as well as in areas of Northern Africa and Asia . Similar to VLF, LF can also be used for navigational radio beacons. It can also be used for maritime ship-to-shore communication, as well as transoceanic air traffic control.
