.. changing the supply voltage fed to a classic 4584 Schmitt trigger type oscillator, the oscillator frequency can be changed over a range of 50:1. A 74HCU04 inverter is used at the output of the 4584 to maintain a ...
.. is RM6 and DK106 is the controller chip. The inductance of the primary winding of the transformer is 2 mH and the switching frequency is 65 kHz. Output regulation is done through a Zener diode, and the controller chip does not need any ...
.. are stubborn things” (John Adams, et al). I added two 50-ohm outputs to the schematic of my published voltage-to-frequency converter (VFC) circuit [ 1 ] (Figure 1). Then, I designed a PCB, purchased the (mostly) surface-mount ...
.. audio content. In this project, I have introduced a compact stereo digital FM transmitter circuit that operates in the frequency range of 87 MHz to 108 MHz. The frequency can be adjusted using two tactile push-buttons, with a 0.1 ...
.. certain to adversely impact the spectacular ripple attenuation cited in Christopher Paul’s original article. Mid-frequency loop gain may also suffer from the heavier loading on C2 and R2 imposed by the reduced R1C value. This ...
.. versus control current is more linear than that of the resistance. This is advantageous, for instance, for VCFs with a frequency response proportional to 1/RC. For music electronics applications, however, exponential control of the ...
.. via R 2 . Figure 1 shows that the µC converts period T into a number by filling the period with clock pulses of frequency f CLK = 1 MHz. It also adds 50 to the result to cancel the offset. The range of the obtained numbers is ...
.. topologies abound for converting current to voltage, voltage to current, voltage to frequency, and frequency to voltage, among other conversions. Figure 1 joins the flock while singing a somewhat ...
.. designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. Figure 1. A digital frequency divider circuit that ...
