Subtractive Synthesis without Filters

چکیده
In this chapter, we take a different approach. In Section 2, we analyze the basics of analog subtractive synthesis, using the simple patch of a square-wave oscillator processed by a low-pass filter with a dynamically variable cutoff frequency. In Section 3, we show how a single mathematical function can model both the oscillator and filter together, and describe an efficient formation for this function (Moorer, 1976; Winhamand & Steiglitz, 1970). Section 4 shows additional applications of this technique.

New Approaches to Digital subtractive synthesis
Computationally efficient oscillator and filtering algorithms for digital subtractive synthesis are discussed. The oscillators algorithms include the recently proposed differentiated parabolic waveform generator and its modification. The algorithm generates a signal that sounds similar to the analog sawtooth waveform, because it suppressed aliasing that occurs due to sampling of a non-bandlimit...
متن کاملPolarization-independent plasmonic subtractive color filtering in ultrathin Ag nanodisks with high transmission.
We demonstrate a TE/TM polarization-independent plasmonic subtractive color filtering scheme employing ultrathin two-dimensional Ag nanodisks. These TE/TM polarization-independent subtractive color filters exhibit small feature sizes (below 200 nm) and high transmission up to 70% in the visible spectral region, superior to previously reported plasmonic color filters. Simulated optical transmiss...
متن کاملDESIGN OF UNEQUAL−LENGTH LINEAR−PHASE FILTER BANKS WITHOUT REDUNDANCY (WedAmPO2)
In this paper, we present a new structure for linear−phase filter banks without redundancy, which have unequal−length filters at each subband. First, we extend the simplified lattice structure of the linear−phase filter bank to the unequal−length linear−phase paraunitary filter bank. In general, the unequal−length linear−phase paraunitary filter bank has equal−length filters at both the analysi...
متن کاملAnalytical Synthesis of Current Mode High-Order OTA-C Filters
Abstract: This paper presents a new general synthesis method for high-order current mode Operational Transconductance Amplifiers and Capacitors, (OTA-C) filters. The method is based on the analytical solution of a single, nth-order generic filter transfer function and the generation of n, number of realizable transfer functions implemented using lossless integrators. The method provides systema...
