Abstract: In view of underwater acoustic complex broadband signal and power amplification matching difficulties of problem, there presenting underwater acoustic broadband power amplifier and matching ...
This article is part of the Ideas for Design Series: Vol. 3, No. 7. This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals ...
Abstract: This article describes the design of a multiphase pulse width modulation (PWM) signal generator model for use in a high-performance class D switching amplifier. Sigma-delta modulation (SDM) ...
This amplifier circuit amplifies audio signals up to 100 watts, suitable for use in high-power audio systems. The circuit includes several stages: an input stage for signal conditioning, a ...
A common PC sound card can be used as a sine/square/triangle function generator, but the output suffers from limited rail-to-rail swing, plus its zero-centered has no dc offset. This circuit overcomes ...
Rohde & Schwarz has enhanced its analog R&S SMB100A mid-range signal generator by adding new frequency options. The R&S SMB-B120/B120L and R&S SMB-B140/B140L options (L versions without step ...
HFDA801A is a 2MHz PWM Class-D audio amplifier with four bridge outputs from STMicroelectronics. High quality sound is claimed by the company: “With a signal-to-noise ratio of 121dB, 120dB dynamic ...
Are you interested in building a 20kHz 2-channel oscilloscope and a 2-channel signal generator for only $20 with minimal effort? Be sure to check out [Jana Marie’s] Instructable that goes over how to ...
STMicroelectronics is using Class-G analogue audio technology to create 117dB S/N ratio, >117dB dynamic range (A-weighted), automotive amplifier. Class-G amplifiers are similar to traditional Class-AB ...
