Simple Digital Logic Probe Circuit
The design of the digital logic probe centers around a pair of complementary bipolar transistors, which, in this application, are used as electronic switches.
The digital logic probe is a diagnostic tool utilized for testing and analyzing digital circuits. The core...
digital switching system
This circuit is capable of controlling one out of 16 devices using two push-to-on switches. An up/down counter functions as the master controller for the system, and visual feedback is provided through LEDs. The circuit employs IC1 (74LS193), which is...
1Ghz Divide-By-N Counter
Counter speeds for CMOS and TTL programmable counters are limited to under 100 MHz. ECL-type devices can approach a few hundred MHz but require significant current. However, using the dual-modulus-prescaling technique in conjunction with phase-locked-loop synthesizer chips that control the...
Astable Flip-flops
The astable flip-flop circuit is a versatile configuration used for creating flashers or generating square waves. A common application is an alternating LED flasher where the LEDs are connected in the emitters instead of the collectors, which is the more...
Flip-Flop Independent Lamp Driver
Assume first that SCR1 is on and SCR2 is off, allowing capacitor CI to be fully charged, with its LMP2 end positive. The state of the circuit can be altered by pressing switch S2. When SCR2 turns on, it capacitively...
1Hz Timebase For Readout And Counter Applications
This counter facilitates the direct readout of frequency-generating equipment by incorporating a 1-Hz time base to latch, reset, and condition the count signal. The design allows for the selection of either polarity. By differentiating, inverting, and ORing the clock pulses...
Sequential Actuator for powering up to four devices
It is common to require the sequential powering of devices, which can involve managing numerous switches that are often in hard-to-reach locations, particularly for informational devices and their connections. This sequential actuator autonomously activates one to four devices in a...
High Precision Digital Pulse Meter Circuit
This compact device, designed primarily for modelers, provides instantaneous readings of pulse duration in milliseconds (ms). It can measure servomotor positions, typically ranging from 1 ms to 2 ms, and can also perform repetitive or non-pulsed measurements, such as the...
Counter circuit diagram of the digital circuit
The digital counter circuit described utilizes an infrared signal to detect moving targets, making it suitable for counting small devices on a production line as they move along a conveyor belt. This circuit can also be employed for various other...
