Hello, How to build Sin wave oscillator for learning??
A 555 will give you a square wave, not a sine wave. I suppose you COULD put a filter on that , but I think you'd be better off just generating a sine wave and amplifying it.
thanks for your answer . Okay , the detail is? Output : sine wave , 5 volt pp , freq 40 khz . Circuit use ic 555 . No any parameters . I want simplest way to made it :) A 555 will produce a rectangular output, and with a little modification, it will produce a 50% duty-cycle square wave, but it will not (...)
Hi all, How to generate a sine wave of frequency 50Hz +/- 10Hz controllable through a POT? the amplitude can be +/- 5to12V, duty cycle 50%. 555 and 566 give only +ve wave forms, i need a wave with alternating polarity. thanks.
This design allows you to vary the output level (using R5) and allows you to switch between square wave or sine output. You can easily design the 30kHz clock source with a 555 timer.
This is my voltage stabalizer that I found in one of those old analogue electronics book. Need it for my project and had built it but it didn't work 68931 I also need to use a h-bridge to convert my DC battery to AC sinewave. The circuit used is shown below 68932 I cant seem to get both of em' workin
I need to full 5 cycles sine wave starting from zero.I need at least to fire once per second.I was thinking if output of two 555 timer mixed (one of them generating (1/20usec ) and another one generating 250Khz to create a tone burst ), which thereafter can be connected to pin no 1 of XR 2206. (i still have to purchase this XR2206 ic):sad:
Just use 555 timer & 4017 to make a quasi sine wave generation to fireup two push pull transistor. Varying the 555 frequency, you can get the different frequency. taking the output from a different tapping of the transformer, you can have different outputs. Now you can approach in two ways. 1. First boost to regulated (...)
the main concern i post this circuit is i want to understand how the output of the circuit can appear as a waveform(sine wave or square wave is not my concern) with a positive and negative cycle. what is the main factor or process that made the output of the the 555 timer which is a a square (...)
Hi, I must do sin wave by IC n555 (not Vco, not Wien, only 555). Frequance range: 100Hz-10kHz Out Voltage: 0-5V Have you any idea? Please you to help me.
My question is why you choose just 8038 , there is much simplier IC for this like 555 or other
