When you’re designing a time signal receiver, there’s no getting around the concept of software-defined radio (SDR). Elektor has published many articles about software for decoding these signals, and here we focus on the required hardware. In this connection, the aim was to manage with a minimum of processing power by using a simple 8-bit microcontroller equipped with peripheral functions that work independently of the CPU. Remarkably enough, at the end of the development process described here, the PIC MCU used was even able to receive and decode two different time signals at the same time.
