Bedside Lamp Timer
The purpose of this circuit is to power a lamp or other apparatus for a specified duration (30 minutes in this case) and then turn it off. It is particularly useful for reading in bed at night, as it automatically...
Duty-Cycle Measurer
An Intersil 7101 31/2-digit A/D converter is utilized to display the duty cycle of a pulse train as a percentage. The frequency range of this circuit is from 100 Hz to 250 kHz. CMOS gates are employed to convert the...
modulation
A reason to modulate a message signal is to match the communication channel's frequency. This is necessary because the information to be sent over the channel is often at a relatively low frequency. For instance, the frequency range of music...
