Mixed Circuits Analog with Digital

Here are some circuits that have both Analog and Digital Signals in them. At one time i wanted to make reed relays, it was a good spot to be in, as it was used in Telecommunications. Even Small Office EPABX systems would have quite a Few of them. It was Simple, [...]

Mixed Electronic Designs

Analog Designs have to handle Linear Signals, Like 2.03 V and 35.3812 mA. Waveforms of all shapes from Straight Line DC Levels to the Jittery and Multi-Frequency Audio Waveforms. Digital Designs manage Digital Signals, Like 0 and 5V Logic levels. All families of digital Logic, have some Threshold Limits and Voltage windows to determine Data [...]

Mixed and Interface Circuits

Mixed and Interface Circuits : Most of the sensor interface and instrument inputs are analog; even if it event based like a limit switch, analog circuit protection and signal conditioning is required before it reaches the level sensitive digital circuit blocks. Starting with Schmitt triggers and to the VCO and A-D Converters, are grades [...]

Building discrete semiconductor and passive designs, using Opamps and Mixed Design Circuits are the first step in electronics. Most consumer Electronics have a high analog circuit content. Even in Embedded Systems the interface design that matters for real time systems is an analog circuit.

Here are some more analog points in my old notes.

The Contact resistance [...]
