The three broad categories of frequency response for amplifiers are AUDIO AMPLIFIER, RF AMPLIFIER, and VIDEO AMPLIFIER. An audio amplifier is designed to amplify frequencies between 15 Hz and 20 kHz. Any amplifier that is designed for this entire band of frequencies or any band of frequencies contained in the audio range is considered to be an audio amplifier. In …

Frequency Response The Frequency Response is an important characteristics for audio amplifier, filter and electronic parts. Introduction. The frequency response shows the behavior of the test object during a frequency change. For almost all objects in electro-technology a frequency response can be measured. The frequency response contains two substantial …

Amplifier circuits are a little bit trickier, but generally speaking: even an average DAC/Amp combo should have a flat frequency response when powering all but the lowest impedance speakers/headphones. Fourier analysis and your music Music producers have their work cut out for them, as changes to emphasis mean changes to sound quality overall.
Understanding Frequency Response - Why it Matters
https://www.alesis.com/kb/article/2227
This is the cornerstone of everything in audio. It all starts and stops with frequency response. Amplifiers, headphones, speakers/monitors, mics, cartridges on turntables, CD and DVD players, they all have to have as close to perfect frequency response as possible, or else they just won’t sound right. Nothing else matters if the frequency response is no good. Can’t make it any …

High frequency Response of CE Amp.: Input RC ckt At the critical frequency, the gain is 3 dB less than its midrange value. Just as with the low frequency response, the critical high frequency, f c , is the frequency at which the capacitive reactance is equal to the total resistance 1 ac e c total C R r ' s // R 1 // R 2 // 2 f C X

amplifier, let’s increase the gain and observe the effect on the frequency response: Remove the external capacitance you added in the previous step and increase the gain by changing the collector resistor to 10kRc . Now re-measure the mid-band gain at 10kHz and find new high-frequency cutoff.

frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency dependent. This can be achieved by modifying either the response of one or more of the amplifier stages, or the response of a negative feedback path.
