We show in the figure how to implement the No-AND or NAND logic function using a general-purpose transistor. The 47 k base resistors and collector can be changed to other supply voltages.
This circuit shows how to control an astable configuration using the 555 IC. The control signal is...
Found in the August 1994 issue of Electronics Now, this CMOS circuit uses the 4046, which is...
This is the transmitter for the previous circuit. We found it in a 90s Electronics Now. The...
