1us Light Pulse Discriminator Plus F to V Converter - This circuit is designed to
detect the narrow 1uS pulses produced by the above amplifier circuit. The clean logic
type pulses produced by the discriminator are then sent to a frequency to voltage
converter. The circuit is designed to process a pulse frequency of 10KHz that is
frequency modulated by voice audio signals. The circuit is described in more detail in
the receiver circuit section of my Handbook of Optical Through the Air Communications.

555 Makes Handy Voltage to time Converter - 02/01/01 EDN-Design Ideas: The circuit
in Figure 1 is a simple, low-cost voltage-to-time converter using ubiquitous 555
timer chip. You can use IC's monostable multivibrator as a voltage-to-time
converter by connecting analog-voltage input to charging resistor, R,
instead of connecting R to VCC. With this modification,.....(design idea added 11/05) |

Circuit Converts Pulse Width to Voltage - 10/25/01 EDN-Design Ideas: The circuit
in Figure 1 converts pulse information to a clean dc voltage by the end of a single
incoming pulse. In another technique, an RC filter can convert a PWM signal to an
averaged dc voltage, but this method is slow in responding. Converting low-duty-cycle
pulse information is slower yet.....(design idea added 1/05) |

Circuit Converts Pulse Width to Voltage #2 - 10/28/99 EDN-Design Ideas: The
circuit is optimized for a positive-going pulse width of1 to2 msec, repeating at
intervals of approximately17 msec. The output produces a voltage of0.95V for a1-msec
pulse to2.25V for a2-msec pulse.....(design idea added 4/02) |

DDS IC Plus Frequency to Voltage Converter Make Low Cost Dac - 02/05/04 EDN-Design
Ideas: Precision DACs are essential in many consumer, industrial, and military
applications, but high-resolution DACs can be costly. Frequency-to-voltage converters
have good nonlinearity specifications—typically, 0.002% for the AD650—and are
inherently monotonic. This Design Idea shows how you can use a frequency-to-voltage
converter and a DDS (direct-digital-synthesizer)chip for precise.....(design idea
