Old analog telephone circuits using carbon microphones seem to be said to have a frequency response of, from various low frequencies which differing reports put at between 275 Hz and 400 Hz, up to various high frequencies, reportedly between 3 and 3.4 kHz, with possibly a peak a around 1 kHz, depending on the manufacturing decade of the carbon mic, and otherwise not …

Frequency response measurement There are two ways to evaluate the cell phone fre-quency response which correspond with two dif-ficulty levels: 1.Using a first mobile phone, a call is made to a second mobile phone and a voice test is performed. Then, the audio plug connector is attached into the audio port of the first phone.

The Frequency Response. Figure 1 shows a plot of level vs. frequency, the so-called “frequency response.” This plot can be produced for any audio component, including mixers, amplifiers, and loudspeakers. It is found on many spec sheets. Figure 1 – The frequency response magnitude of a band-pass filter.

Frequency Response To measure the frequency response we measure a set of 61 tones from 20 Hz to 20 kHz. All of these are then equalized to 1 kHz so we can see the maximum deviation from that level....

In the real world, you’ll often see frequency response specifications quote a range of frequencies, such as 20Hz-20 kHz, followed by the amount of variation in the frequency response quoted in decibels, such as +/- 6 dB.

Telephone line frequency response. Typical telephone line has frequency response of 300 Hz to 3400 Hz. The signal starts to attenuate in the frequencies below 300 Hz because of the AC coupling of audio signals (audio signal goes trough capacitors and transformers).

Back in the bad old steam-driven days of rotary dials and carbon microphones the frequency response of a telephone connection was something like 300Hz-3.5kHz. Analog relay contact telephone systems have a bandwidth of something like 5hz to over 25KHz. In fact, before the modern multi-band DSP encoded modem, in the really early 90's, USRobotics had a modem …

A frequency response graph (or chart) is created by testing the headphones/earphones/speakers in recording studios. Various frequencies are played through the headphones placed on a recording device. The audio output is recorded and plotted as a graph or a chart. The volume and decibels (dB) of the reproduced sound at every frequency are marked ...
