How to design a ramp frequency circuit

WebRun a Transient Test of the ramp generator with the following parameters: You need 16 clock cycles to cover all the counter states. Therefore, the period of the ramp generator is T = 16ΔT = 16ms, and its frequency is f 0 = 1/ (16ΔT) = 1/ (16ms) = 62.5Hz, where ΔT is the clock period. The output voltage graph is shown in the figure below. WebApr 4, 2002 · Microprocessors can easily generate the needed ramp-up and then ramp-down signals, often called a trapezoidal profile, but in any circuit without a microprocessor, this ramp is difficult to generate. The 555-based bistable circuit in Figure 1 can easily generate a pseudo-trapezoidal move profile.
