Audio Amplifier and Signal Processing Fundamentals
In an amplifier, the maximum input level is: The maximum allowable stress in your entry without causing saturation distortion.
The mixing of two frequencies within the amplifier is called: Intermodulation distortion.
The order of a filter indicates: The selectivity of the filter.
Speaking of the resonant frequency of a filter, we mean: The frequency of best response.
The loudspeaker capable of reproducing frequencies from 200 Hz to 8 kHz is: The Squawk.
The dynamic range of a signal is: The amplitude difference between weaker and stronger sounds.
The following figure shows: The response of a tone control.
What is a pending processor elbow?: A compressor.
In ascending order, the numbered items in the following figure are called: Pan, activator, level control.
The quality factor Q of a filter: Both a and c are correct answers.
The RIAA equalization is used in: The phono input of an amplifier.
The following figure shows: The impedance of a loudspeaker.
In an audio mixer, shipments are: The auxiliary outputs.
To prevent a microphone from capturing sounds routed to other nearby microphones, we use: A gate.
The parameter that indicates the capacity of the power amplifier to provide instantaneous current is called: Buffer.
The following figure shows: A crossover.
The vinyl uses a stored procedure: Mechanical.
In a magnetic system, the air gap is: In the magnetic head.
The squeeze on higher peaks and lower signal gets the figure below is called: Saturation distortion.
The first zero of the magnetic tape recording provides a signal whose wavelength is equal to: Twice the width of the gap.
The noise reduction system that divides the audio spectrum into four sub-bands is called: Dolby A.
To limit the frequency of the digital frame in a DAT system, 8 to 10 modulation is applied.
Which statement is not correct?: The DAT signal is sampled at 44.1 kHz by default.
To bring digital signals to support a CD, the two previous encodings (FSM, NRZI) are used.
The mission of the collimating lens is: To keep the beams parallel.
The psychoacoustic masking feature is used by the decoding system: ATRAC.
The remanent magnetization is: To keep the information stored on tape.
The frequency response of the magnetic head is determined by: The auxiliary signal polarization.
The following compression curves belong to the Dolby system versions: Dashed line = B, Solid line = C.
The sampling frequency of an analog/digital converter should be: Greater than or equal to twice the maximum frequency to be sampled.
In a DAT system, what is the ICRC?: The set of cyclic redundancy two systems, interlocking system.
In a DAT system, each helical track also contains: Two auxiliary tracks, Two areas of subcodes.
The collimating lens of a CD system is responsible for: Keeping the bundles in parallel.
The system that handles the large displacement of the optical group jumps in a CD is: The sled servo.
The ATRAC encoding scheme is proper for: Minidisc.
The reading of data on a recordable mini-disc is based on: A magneto-optical system.
The mission of the diffraction grating is: To divide the main beam into three secondary beams.
