# Electronic Circuit Design Programs

Programs for computer-aided-design of active filters (Bessel, Butterworth, Chebyshev). Also design pads and attenuators; state-variable, staggertuned, and notch filters; amplifiers, 555 timers, yagi antennas; regulators; and heat sink parameters. Many draw schematic on screen. 16K.
