Digital Signal Processing Questions & Answers

Digital Signal Processing Questions & Answers (HPF) High Pass Filter or Low-Cut filter - CORRECT ANSWER - Passes high frequencies and attenuates lows. 3 General categories - CORRECT ANSWER - Spectral (um) (Frequency based) Dynamic Range (Amplitude based) Time based & Modulation Acoustic Chamber - CORRECT ANSWER - A highly reverberant room with reflective surfaces. Advantages: Accurate, natural, acoustic reverb Disadvantages: Cost of Space Active - CORRECT ANSWER - Active components are capable of gain. Using transistors Amps or tubes Attenuation - CORRECT ANSWER - Refers to any reduction in the strength of a signal. Auto Logic Control - CORRECT ANSWER - Intelligent circuit analyzes the signal and automatically sets reaction times. Auto Release - CORRECT ANSWER - Determines release rate according to program dynamics. Band-Pass Filter - CORRECT ANSWER - Combining a HPF and a LPF he bandwidth of a band pass filter is determined by the cutoff frequencies of the HPF and the LPF. The frequency band within the cutoff frequencies is called the pass-band. Band-Stop Filter - CORRECT ANSWER - Is made the same way by combining a HPF and a LPF. The frequency band within the cutoff frequencies is called the stop-band. Boost - CORRECT ANSWER - Increase amplitude by a certain amount of dB. Brickwall Limiter - CORRECT ANSWER - 100:1 Ratio By-pass/Gate - CORRECT ANSWER - Allows the user to activate or bypass the gate. Center Frequency - CORRECT ANSWER - The frequency at which the peak filter has the most effect on the signal. Is variable. The climactic point of the filter curve/shape. Chorus/Doubling - CORRECT ANSWER - 15 - 40ms
