Simple IR Receiver Schematic Circuit Diagram

This circuit has been designed to complement the ‘Simple IR Transmitter’ and to decode its transmitted signals. The similarity to the transmitter can be clearly seen: the received data is decoded by a shift register (74HC4094), which again is clocked by a counter/oscillator (74HC4060). The receiver is started by the first edge from the IR-receiver[…]

Wideband Waveform Generator Schematic Circuit Diagram

This circuit is designed to provide a wideband digital sine wave signal source. Its main feature is that because it synthesizes the signal in 32 steps, no low-pass filter is required to suppress the odd harmonics. A well-known method for synthesizing a sine wave under control of an input frequency is to apply a low-pass[…]
