  • Converts a Square Wave input signal into a Voltage  - This is a test circuit converts a square wave input signal into a voltage. But, the voltage produced is proportional to the time between edges (period) of the signal, not the frequency. The range is from 100uS to to 10mS, which produces a voltage from 100mV to 10 volts. Other scale factors are also possible . . . [Hobby Circuit designed by David A. Johnson P.E.,  06/04/00]
  • Pulse Period to Voltage Converter  -  This is a test circuit converts a square wave input signal into a voltage. But, the voltage produced is proportional to the time between edges (period) of the signal, not the frequency. The range is from 100uS to to 10mS, which produces a voltage from 100mV to 10 volts.

555 makes handy voltage-to-time converter  -  02/01/01 EDN Design Idea   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 . . .  [by J Jayapandian, IGCAR, Tamil Nadu, India]

Circuit converts pulse width to voltage  -  10/25/01  EDN Design Idea   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 respo. . .  [by James Mahoney, Linear Technology Corp, Milpitas, CA]

Converter Ignores Power-Supply Variation  -  01/05/95 EDN Design Idea   The simple period-to-frequency converter in Fig 1 uses a dual-slope ADC (IC2) to drive a 3. 5-digit display. One medical application uses the circuit to convert the time interval between two heartbeats to a rate of number per minute. . . .  [by Samuel Kerem, Infrared Fiber Systems Inc, Silver Spring, MD]
