Four-frequency circuit

Published:2011/6/5 0:13:00 Author:John | Keyword: Four-frequency

The figure is for N = two-quarter frequency ratio circuit. The circuit is often formed by double-D-FF or two JK-FF devices. Frequency division ratio of n> 4 circuit is often achieved by counter (for example a preset counter), which is generally without the need to combine a single FF. The output duty cycle of the following divider circuit is 50%. It can be formed by D-FF or JK-FF. The JK-FF divider circuit tends to achieve a parallel and synchronous work easily. So such circuits can be suitable for high frequency applications. If the pin R, S (P) and other pins in FF are not used, it is necessary to connect to non-effective power or ground line according to the its functional requirements.   (View)

RC series-parallel frequency selection network oscillator circuit

Published:2011/6/4 23:39:00 Author:John | Keyword: frequency selection network

Disconnect the RC series-parallel network to measure amplifier’s quiescent point and its voltage gain. Disconnect the RC series-parallel network and the amplifier. Apply the sinusoidal signal of the function signal generator into the RC series-parallel network. Keep the signal amplitude still (about 3V). The frequency changes from low to high, so the output amplitude of RC series-parallel network would change. When the signal source reaches a certain frequency, the output of RC series-parallel network will reach the maximum value (about 1V). And when the input and output are with the phase, the signal source frequency is .   (View)
