This is a collection of projects and resources for PNTS-9000 Industries.
A test oscillator project for testing AM broadcast receivers. It generates a 1 kHz tone modulated onto a 535 kHz and 455 kHz carrier, which can be used to test the sensitivity and selectivity of AM radios.
A focus on the Schmitt trigger oscillator, which is used in our RF Test Oscillator project. This project explores the design and operation of Schmitt trigger oscillators, including frequency calculations.
