Abstract:
The analysis of a noncollinear acousto-optic tunable filter commonly found in the literature is based on an approximation for the birefringence of the interaction material. It is demonstrated that this approximation leads to a significant error in calculating the optimum incident angle for a device, which can seriously degrade its performance if a fixed output beam angle is required. An alternative, exact analysis is presented and compared with experimental results.

01:23Design Example
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...
01:25Active Filters
Active filters are electronic circuits that use operational amplifiers (op-amps), resistors, and capacitors to filter out unwanted frequency components from a signal. A first-order low-pass active filter is designed to pass signals with a frequency lower than a certain cutoff frequency and attenuate frequencies higher than that cutoff frequency. The transfer function for a first-order low-pass active filter is:
