Frequency Modulation (FM)

In telecommunications and signal processing, frequency modulation (FM) conveys information over a carrier wave by varying its instantaneous frequency. This contrasts with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant. In analog applications, the difference between the instantaneous and the base frequency of the carrier is directly proportional to the instantaneous value of the input-signal amplitude. Digital data can be sent by shifting the carrier's frequency among a range of settings, a technique known as frequency-shift keying. FSK (digital FM) is widely used in data and fax modems. Morse code transmission has been sent this way, and FASK was used in early telephone-line modems. Radio teletype also uses FSK. FM modulation is also used in telemetry, radar, seismic prospecting and newborn EEG seizure monitoring. Frequency modulation is known as phase modulation when the carrier phase modulation is the time integral of the FM signal. FM is widely used for broadcasting music and speech, two-way radio systems, magnetic tape-recording systems and some video-transmission systems. In radio systems, frequency modulation with sufficient bandwidth provides an advantage in cancelling naturally-occurring noise.

My Favorite Radio Station

Every time I heard the word “tugstugan na” one thing came into my mind and that was my favorite radio station "barangay ls 97.1."

This station is not boring because of the Dj’s. 

The Dj's are not corny and exaggerated. Even though their jokes are corny and waley, you will still laugh because they can deliver it nicely. The tune of their voice are funny and the way they deliver it. Their advice have sense and you can get some moral knowledge.

The programs that I always listened to are:

• Potpot and Friends
• Balita sa Barangay
• Kwentong Barangay
• Talk to Papa
• Bida sa Barangay
• Batak-balitaktak (Sponsored by: Revicon Forte: Lakas Na 'Di Umaayaw)
• Wanted Sweetheart
• Big 10
• Mark Bautista Bakit
• Barangay Love Stories
• Barangay Love Songs

The Disc Jockeys or Dj's are:

• Papa Baldo
• Papa Bodjie
• Papa Dan (formerly Dan the Man/Mr. Dreamboy)
• Papa Dudut
• Papa Jepoy
• Papa Kiko
• Papa Obet
• Papa Tolits
• Mama Belle
• Mama Cy (Pinch-hitter)
• Ate Liza (formerly Hot Lips Leeza/Churvilyn)
• Chikotita

Barangay LS 97.1 is the best among the rest<3

Pandora Radio History

Pandora Radio is an automated music recommendation service and custodian of the Music Genome Project available only in the United States. The service plays musical selections similar to song suggestions entered by a user. The user provides positive or negative feedback for songs chosen by the service, which are taken into account for future selections.

While listening, users are offered the ability to buy the songs or albums at various online retailers. Over 400 different musical attributes are considered when selecting the next song. These 400 attributes are combined into larger groups called focus traits. There are 2,000 focus traits. Examples of these are rhythm syncopation, key tonality, vocal harmonies, and displayed instrumental proficiency.

The Pandora media player is based on OpenLaszlo. Pandora can also be accessed through many stand-alone players, such as the Roku DVP (formerly Netflix player) Reciva-based radios (from companies like Grace Digital, Sanyo, and Sangean), Frontier Silicon-based connected audio systems, Slim Devices, and Sonos product(s). On July 11, 2008, Pandora launched a mobile version of their software for the Apple iPhone, iPad, and iPod touch through the iTunes App Store. Pandora is also available for Android phones, BlackBerry platforms, HP webOS(used on the Palm Pre, Palm Pixi, Palm Pre 2, and HP Veer), and Windows Mobile devices. Pandora was the provider for MSN Radio until MSN discontinued their internet radio service on June 18, 2008. A modified version of Pandora has been made available for Sprint Nextel.

The service has two subscription plans: a free subscription supported by advertisements, and a fee-based subscription without ads. There are also advertisements in Pandora Mobile for mobile phones and the Pandora in The Home computer appliance. Most users choose the free subscription. As of IPO, Pandora had 80,000 artists, 800,000 tracks in its library and 80 million users.

In May 2010, Pandora was named in Lead411's 2010 Hottest San Francisco Companies list.In January 2011, Pandora met with bankers to consider a possible $100 million IPO. The company filed with the SEC for a $100mm IPO on February 11, 2011 and officially began trading on the New York Stock Exchange with ticker symbol "P" on June 15, 2011 at a price of $16/share. This gave them a valuation of nearly $2.6 billion.

During its 2011 fiscal year, Pandora reported $138 million in revenue with a $1.8 million net loss, excluding the cost of a special dividend associated with the IPO.
